as part of my name is ginger Kent's I don't have any slides except that 1 which is blue and I'm here to talk to you about the OpenCalais standard which isn't a real standard but I'm working on it and as I said no slides so will keep the lights up so that we can all see each other because I tend to fall asleep when it's dark and someone rambles on for half an hour so I'm assuming you might to the sample and I want you to see Awakenings so so I have a rough action plan for the sort of but we'll see where it gets so the OpenCalais standard is effectively supposed to be a way to we translate color of across media traditional color management is about translating between different digital media this is about print media are food media Water media any media that's not digital so about standardizing color across basically everything anything that can be tolerated I want to color I and I want that to translatable into a reasonable deal paths in the reasonable digital facsimile this is result and so you might think 0 gosh the content and it's a similar but it's very specifically not centered so why would anyone want you that's what's the point of having an open closed and and and for me the point of the eventually standard is that embody I was working in prepress at a newspaper in a largely floss workflow in Inkscape begins and so on and there is illustrations for them and every once in a while managing editor would come to me and say will we have color on this page but it's not for color it spent on we have this orange because some advertisers bought orange and so can you take the illustration that you're putting on the other page and make it a specific shouldn't as an orange which would require from a breach in my workflow and going into the domain and making an orange because of course for the actually has the proper Pentonville built into it so that me and and then upon further examination it it turned out that the Canadian flag I'm from Canada by the way has attendance specification for the shade of red ones believe and I'm not particularly but that got me a little bit to think that nothing is sacred tend to even has its hands my flag sales I have so essentially when I was served as a feasibility study where the I looks at how the heck this would happen whether or not it's possible to come up with an open and the and open standard for floors graphics applications in my feasibility study Canada is there's no way this is possible it would be incredibly foolish to do that so I haven't done during I and II and liminality and actually this is I should appear less is a given another and I got ambushed when people found the OpenCalais centered on my website and was told that I had to do it so here I am so so in very game from that's what do design professionals Weaver Graphics people what does anyone gained from an and sharing betray myself and pull out all of the terrible little academic words are you gain agency 1st of all the ability to actually control the destiny of your tools which is a very hot topic around here as far as I know and yet so agency and control that's the number 1 and it's quite big and quite important because other people shouldn't be defining for you what your color is because for goodness sake it's visible light ch in Ireland it's big it's in there is everywhere and we should all be controlling and not hands and there's extensibility as well because pension is a fairly stable standard and once again we have no say in how it's extended when they had Nicolas will influence the with an open calais standard there is the possibility of having allowing users 11 stakeholders inside which points get added to the and to me that's a very big deal and finally of course there's the refried medical on which is that it would be really nice to be able to do spot color enough flask graphics Workshop workflow I would love to know what has to hop into Photoshop every time I want the spot color and so that's why it would begin and that's why it matters so the next question is who might use that and we're don't the 1st people this is not against that people who deal with print and I know people say that print design but I this expression that that it death is greatly exaggerated and whatever Mark Twain actually said you way print still around but print is yes Princess changing thank you but that's not the only group of people who have to look at because that's the most difficult 1 designers the people who need a thousand colors a nice-looking full of those colors In order to do their work and to get to that group we needed in manufacturers on board and we need print shops on board and that's incredibly difficult that's the scenario that made me think this is impossible but there's low-hanging fruit to use a terrible business term the low-hanging fruit is academia I'm survey and my every Sarah again but take archaeologists for example they use Munsell color charts someone solves another color specification owned by the same parent commitment and his and by and archaeologists have these little will charts with a lot of she the brown on them and holds next to you brown and they use these shorts defined declared same thing for botanists and other people in the natural sciences you might define the shade of green of a leaf mold using concepts right in a patent for a new cultural fruit you might define its red using a Pantone color and so these are groups nature so academic people who were generally interested in open standards and open anything you know that's where the open access movement is coming from so that's low-hanging fruit there's also part of it I love hobbyists and audience there are people screen there people who know that there are people who do all of these exciting things that require culture and we know the hobbyists are already using foster because well it's easier you know they can get at it without having to lay out a huge amount of money so obviously a good thing they're more low-hanging fruit and there are already using things like Inkscape at thing describe appearance and who using state to drive vectors to capital things for this guy books which there's my mind a little bit because I don't like scrapbooking but it's accepting that they're doing that and then also this text at all because of course and text all its it's interesting cell and it's also very dependent and it's also a good candidate for the low-hanging fruit color approach the next question is
how it works we have these people who might use that we have this scenario have a have to make it work and that the difficult that but I think it's doable and I have an action plan I so the 1st problem that we encounter in color standardization is the problem of how do you define your basin of covariance because seem like a doesn't do the job right the reason we have spot color the reason we have matching systems is because he like isn't good enough it misses some comments so for example Caucasian skin tones are translated very well into see again so that's a problem it means that you can print cosmetics ads with people with money skin it just it looks really bad fluorescence as well and also as a specialist conference they don't exist in until 1 can see needed extra banks in yourself and so the problem I've been facing is when looking at any How do we know that across manufacturers we have a gamut of thinks that's actually the same and we don't know that and so that's a
problem so my approach to this issue in use standards that already exist do after things like of in North America the FT seed couldn't food clothing and ice essentially the paradise admit the standard for which is administered by the US FDA and they're incredibly highly regulated and there's not that the chemical and in Europe was of those a actually translatable directly into each other's so that's again the standard here so those that and from 15 dies which and do things like make screen-printing which have enough to make your and dying because of course if he takes an citric acid and I have some water and neural you can turn weight urine into the Ljubljana ready not whatever you want or in specific case you can use cared I out I was actually hoping to be standing up here like a chameleon blending of my background because a a couple weeks ago I made this blue haired and that's color matched to that very color behind me which is also color of the UCS logo unfortunately I didn't put enough citric acid and so it didn't stick the washing but imagine that have so there is that there's all sorts of nice little options with 15 but there's lots of other challenges
standardization is the weight issue I hate the way issue the problem is that it's impossible to define white and in order to define a color standard you need to be able to define white because the base of the colors determines the final filter so there is way to
grapple with and I'm not sure how to grapple with light there is the which have slightly address what I call the roll-your-own versus pre-made discussion do we do with things that already exist do we're or do we make the screen printing inks and investing it's pretty fun I had recommended but not of so again we can just specialist groups yeah the enthusiastic and go for it now there is a thing that bothers me greatly and in the presentation was originally planning to do I have a slide of that and is a really good looking slide I I I just didn't feel like doing 100 of the slides for today which is what I normally do but this slide had the words you can standardize beats and a picture of a beat and is a really nice picture of the Sumatran on and the point to be care bits is that as a you know a rate thinking contemporary 1st I should be thinking that we should be going natural with that's why use these notches nasty dies that can cause hyperactivity in children with cancer and whatever else they do doing when we should be doing next natural fuzzy things and the problem is you can't standardize beats if you're going from a natural diet there's going to be too much color radiation and that's a problem so nasty things instead I to during the time and losing my train of thought a little that I should be around when the so this measurement issues as well and all this by the way all of these issues that I'm telling you that haven't grand purpose which will get to after the measuring insurance because these are all people problems so measuring issues involve things like if you're working with it takes the incredibly tiny amount of it to make a call the resulting 10 to the ground less than 10 to the ground and most cheap easily available skills don't do that there is the color measurement problem which I discussed in great and frustrating length with some people here on which is that you can't just point a little RGB sensor at a swatch of color under normal light whatever normal letters and expect to come over the and accurate color reproducible so we have this sort of spectra reflective physics issues actually can send the physics which irritates me because I don't like the sex but so all of these are people problems times in 8 floors project the whole point is that I'm not sitting in my basement alone you know under the fluorescent lights with no air flow bad ventilation respirator on doing this 11 the point is that other people should be invited by unrelated to so many other projects this 1 is actually all the individual in normal proliferation you have a centralized statement you have a bunch of course and just hang out together In the in 1 area do think is based on a specific and often extensive set of little standards you have been working with real spectrometers the cost tens of thousands of dollars that find words so that measure the spectrum of light bouncing off of swatch you have all of things so haven't had do we take something sort of only high-tech is color friction and you wouldn't think it sidesteps because any kid conceit pain and makes a yellow and a red and get an orange but it's it's not so simple although I wish it were and I'm hoping to make it possible with a given set of things so the question is with the way problem with the measurement problems with the standardized gamut problem how the heck does this thing get opened up to everyone has to say she people with this set of tools you can make a color and then you can submit that cover and then you can see that a lot of reality so this is a problem so grappling with event other than be incredibly top down and see you must use this paper you must use the spectrometer you must must must must not so you must calibrate this way I don't think that's gonna fly others that the expression is like herding cats it would be like herding cats to tell people who and open source that they must do something my way that that's crazy talk so there is that so these are the problems these are the
issues involved in that and the sort of potential ways of making it happen but the concrete things I know people like
concrete things so In my remaining 5 minutes I will tell you but the concrete events I'm working on some proof of concept now the here that I mentioned this 1 there is
yet dies for and here I think fiddling around lot strand of seeing in the lab I feel so Signed sealed off I've been fiddling around dying in Europe and attempting to standardize on color because you're held right if anyone designing who needs we have a couple when you make a sweater you generally by more and then you need because of the dialog problems and the dialog problem is that with this idea and that's supposed to be the same as with 1 and you know you're until a number in 2 dialogs in the dialog is you know choose this giant vat of dye neuron you do it once you go back and do it again you're not guaranteed that the code'll be exactly the same certainly working on the on problem because I think it's compelling and I think if I can fix your I can do anything so there's also the urinating should you choose a really running which is quite fond of STAT diet little citric acid little bit of extended base for screen-printing and your set so the 0 I need to get a tutorial upon that actually expected tutorials and also the Web segments of Indian so rolling around coming up with your own dice based on the the above-mentioned and see colors which again I'm not sure that's the right tactics but it's the static and currently using because if I sat and thought about it all the edges we paralyzed summaries will take action and there is the homebrew measurement tools states you really exciting things happening I there's 80 you little RGB center being works on at the university of Toronto and the critical nature lab which is in the basement good things happen in basements and by Dr. Marco like really have to give an extreme here a year so he is attempting to make an RGB sensor that well measures RGB data from physical swatch so that that's going on community putting up its this Arduino only putting up the kids so anyone who wants to have a look at it can fixed it and then there's um collaborator Robert students and senior relation but he is relation I'm working on a home prespectrometer made pipe and torn apart webcams and all sorts of fun things and again the website has a link to that system when I put you the website you'll be able to look at that and build your own spectrometry so that's the conclusion of that my rambling introduction for you to the OpenCalais standard and I have written in some sort of sense because I'm not sure and be thinking gender and this time for a few questions so we take to and would like to ask a question good have you given any thought to measurement of transmissive media other than reflective media for like filters croak filters so that that's what they do I have to certain extent although 1 thing that makes me happy is that there are already pretty did open standards for transmissive media if we're talking about the same thing and mean there's all the standards for light on although I haven't gotten into the thorny issue of Yemen while you're haven't been thought to be on the fact that I know the standard exists already for certain transmissive media and although not all of them but water which is a hellish thing to think about the quizzes beasts the impossible to measure not trust me I'm not certain of liquids that would be but yet no thought to it really have to be on the question there was I would like to ask that you all know how to human perception as you know each I O feature humanistic somehow different so how can you take this thinks to your open standards or you know there's there's some or it's more like ideal physical human standard thing or how to count you basically you basically hit on the head the 2nd time i've well I cared deeply about how humans see color I and well it matters to certain extent how we perceive I'm relying on machines to do my work for me because I think that they can do a better job of actually tell me what the tolerance and I can because if I look at that as it's blue you might not think it's clear cells a machine will tell me what the spectral data is which is a little more reliable using the so it's relying on machine a good thing good time so we take 2 more questions his moral operational questions as an answer to the previous 1 all that stuff was worked out in 1931 to 1976 so going from a spectrum to how standardize I view things so the 2 views of you're just saying colors the same is actually solve problem pretty much I was just wondering how you would to add it to the to help with this project and also if anybody in here would be interested in things OK well the the whole thing is that we have been giving thought to I'm an incredibly disorganized person which is a problem and actually greater than the state John Phillips thank you so much for making me make the website there wouldn't be a website if John hadn't stepped in and pushed me so now the 1st cell phone need is making someone getting someone to make me organize organizations which is an apple that all I'm going to try to get some actual sort of vectors for collaboration going on at the moment he can come up to me and I'll send you a business card and you can even on the and we can talk I know that's not the most efficient way to hold that there's a wiki even perceptron which the there is a I think there is a list of action points on the web said if there isn't I'm going to put 1 up I that's the yeah that's the whole and if anyone has good answers about how to define weight beyond missing by this type of paper I'd love to hear that or any of those issues that energy of western number 5 I through here and you have to the use of all you and you continue until then you yeah yeah absolutely so the website is open color . org and that's color with the you so that's open see below will blow you are the
