The source color is in the top left corner and below it are colors darker than it ordered by lightness descending from top left to bottom right. The hue of all the colors is supposed to be similar but there is so much variance in the hue that really only 20% of these colors are usable.
This image would be printed out and if one of the colors is more accurate after printing, then the source color in the original art would be replaced with that other more accurate color.
- gus_massa 3y agoI think you have too much samples in your databas. I think it's better to sample a much smaller range like 4x4x4x4 in the CYMK space, and interpolate the other values. (Perhaps 4x4x4x4 is too low, and you should use 16x16x16x16, or sample using an uneven grid because the easy grid will probably be full of dark brown versions.) Anyway, it looks like someone else gave a better hint and you were able to solve your problem :) https://news.ycombinator.com/item?id=37643761 https://news.ycombinator.com/item?id=37643761 --- If some day you have some free time, it would be nice to read a blog post explaining the problem and the solution. If you add some photos it could get some traction here (or not, nobody is sure what gets traction).
