Colors are bad

[gellyfisher]

Green doesn't ever get drawn. Probably some bug in the color distance. I took some code from online and put it together to get a good color distance. see gellyfisher patch 1 branch

blue is never drawn either

Thanks, @gellyfisher. I'm having trouble reproducing green not drawing. Can you attach an image that demonstrates the problem?

I'll draw this color gradient in skribbl.io:

Here is the existing color distance function:

Here is the color distance function you propose:

I'm happy to change the color distance function to improve accuracy. I'm having trouble deciding whether the proposed function is an improvement though. Can you help convince me?

Also seems like lots of pink, but idk, heres a sans image vs what it draws:

No blue eye

Yeah that and I get this orange instead of green if I use your code (I changed the drawing order though so that it's less messy)

while if I use my code (https://github.com/gellyfisher/skribbl-io-autodraw/blob/master/color-helper.js) then I get

Thanks! I'll investigate further.

I tried out your code and get more detailed images, still missing blues.

Its not perfectly blue either in the original. Maybe theres just not a color that's close to its eye color? Maybe try to use something more colorful for testing

Using CIEDE2000 now:

Light shades of blue resolve to light gray:

Not perfect.
