<html><body><span style="font-family:Verdana; color:#000000; font-size:10pt;"><div>Good morning Ashleigh,</div><div>I have been looking around and trying to figure out what kind of information I can get from the app "Color Assist" and the color picker in Affinity Photo - an equivalent software to Photo Shop.</div><div>I found a web site at: <a href="http://colorizer.org">http://colorizer.org</a></div><div>This site is fascinating but I don't know how accessible it is. It goes into more formats for light based color scales than I even knew existed. It has information like this:</div><h3 style="">RGB (Red Green Blue)</h3><div style=""></div><div id="rgb" style=""><div style="">The <strong>RGB</strong> (<strong>R</strong>ed, <strong>G</strong>reen, <strong>B</strong>lue) color model is the most known, and the most used every day. It defines a color space in terms of three components:</div><ul style=""><li><strong>R</strong>ed, which ranges from 0-255 </li><li><strong>G</strong>reen, which ranges from 0-255 </li><li><strong>B</strong>lue, which ranges from 0-255 </li></ul><div style="">The <strong>RGB</strong> color model is an additive one. In other words, <strong>R</strong>ed, <strong>G</strong>reen and <strong>B</strong>lue values (known as the three primary colors) are combined to reproduce other colors.<br>For example, the color "Red" can be represented as [R=255, G=0, B=0], "Violet" as [R=238, G=130, B=238], etc.</div></div><div><span style="">Its common graphic representation is the following image:</span></div><div><span style="">Ashley this is my verbal description of the picture so please forgive if it is not clear. Let me know and I will try again. Ann</span></div><div>The image is of three partially over lapping circles in a triangular arrangement. The top circle is an intense red, the right and down circle (which overlaps the first circle about 1/3) is pure blue and the third circle on the lower left (which overlaps both the other circles about 1/3) is pure green. </div><div>The space where the red and green overlaps produces yellow.</div><div>The space where the red and blue over laps produces magenta</div><div>the space where the green and blue overlaps produces light blue. </div><div>The space where all three overlap produces white light.</div><div>This is a subtractive color space, all colors mixed together create white. </div><div><br></div><div>A computer uses this kind of information to mix and identify color. But if you get on the site you will also learn that it uses any number of other formulas to define and identify colors. In the light scale. </div><div><br></div><div>However when we are identifying something like the color of a quilt fabric we are dealing with a whole different kettle of fish. Fabric, paints, print on page are all in the pigment space, not light. The scale is Red, Yellow and Blue and it is an additive color scale meaning all colors added together, theoretically, produce black. The pigments are created by adding different amounts of the primary colors to create a secondary color. Which are:</div><div>Red and yellow makes orange.</div><div>Blue and yellow makes green.</div><div>Red and blue makes purple. </div><div>Red, yellow and blue make black. I say theoretically because pigments are not pure colors historically even thought there are so pretty good chemical mixtures that do come fairly close.</div><div><br></div><div>So when you take a pigmented object and identify it with a computer you are switching format for color identification, going from pigment - red yellow blue to light - red, green, blue. I was playing around with my color picker yesterday by taking a photograph of a swatch of striped fabric that I would easily identify visually as a dark blue striped fabric. 85% of the threads is an indigo color and the other 15% is light blue threads. But because the fabric reflects light, parts of the photograph were much darker and identified as black, the parts in shadow, and other parts identified as very light grey, highlights.</div><div><br></div><div>So I tried an amalgamation of around 200 pixels but because the photo had all these highlights and shadows reflecting from fabric in addition to the color of the fabric dies it came back as either a light grey or a dark grey when they were all mixed together. So I went to single pixels and maybe with some sort of systematic scanning, pixel by pixel you could come up with a rather sophisticated idea of what the color schema is for a piece of fabric. </div><div><br></div><div>And with that information I think you could determine what fabrics would go together. Or at least it would be really interesting to see what kinds of matches you are making. I know when I help my sister, she really doesn't need my help, selecting fabrics for the quilts she makes I think what we are actually doing is finding little bits of color in the different patterns that match or are complimentary to bits of color in another fabric. For instance it might be a fabric I would identify as orange but it is a floral print. So we start looking for a nice match and find a green print but it has brown branches that match perfectly with some of the brown leaves in the orange print and they look good together.</div><div><br></div><div>You really have me thinking here because I am not sure if that is all that is happening or if there is more that I am just not aware of. I do know that people frequently don't agree on what "goes together". Thinking back I know that was one of the things we were doing but were we also doing something else? I am not sure.</div><div><br></div><div>I am pretty sure that you would get much clearer results with a scanner rather than a photo of your fabric if you want to play around with this system and see what you can learn. I don't have a scanner so I can't be sure. Maybe some one on this list could help with scans if you don't have one either. </div><div><br></div><div>OK those are my thoughts for now. If this is answering any questions you have or if I am way off let me know. All best, Ann</div><div><br></div><div> </div><div><br></div><div><span style="font-family: andale mono,times;">Ann Cunningham</span></div><div><span style="font-family: andale mono,times;"><span style="font-size: 12pt;"><em><span style="font-size: 10pt;">Tactile Art </span></em></span></span></div><div><span style="font-family: andale mono,times;">303 887-1713</span></div><div><span style="font-family: andale mono,times;"><a href="mailto:ann@acunningham.com">ann@acunningham.com</a></span></div><div><span style="font-family: andale mono,times;"><a href="http://www.acunningham.com">http://www.acunningham.com</a></span></div><div><span style="font-family: andale mono,times;"><a href="http://www.sensationalbooks.com">http://www.sensationalbooks.com</a> </span></div><div><br><br></div>

Hi Ann,<br>
<br>
Thanks so much for your quick reply. I will certainly give the app you<br>
suggested a try. I have another app I've used, I can't think of the<br>
name, but it is not very accurate. I've also used the color option on<br>
the SEeingAI app. The issue I'm finding is the need to have almost<br>
perfect and consistent lighting to get accurate readings each time.<br>
For instance, it will read the color as red, than pink, than bright<br>
red, etc.<br>
<br>
The main reason I'm interested in the color wheel, however, is not<br>
necessarily color detection. The wheel is supposed to be laid out in a<br>
way that allows users to locate colors on the wheel, and use their<br>
locations to identify analogous colors, complementary colors, etc. I<br>
am looking for a good method of identifying when different colors fit<br>
with each other. Especially when you start to get away from the super<br>
basic colors like blue or green, and into more variants such as aqua<br>
or teal.<br>
<br>
I hope that all makes sense.<br>
<br>
Thanks again!<br>
<br>
