surprisingly fun.

not knowing anything about color, i will admit i am a bit confused. i scored 0.0034 and was told "if you're not already calibrating displays for a living, you're leaving money on the table". which, to me, implied i did quite well!

but, reading the scores posted here, most people are doing a lot better than me. i doubt all of us are crazy good...

so, i assume the front page is a typo: "most people land around 0.02" (should be 0.002, not 0.02)? if yes, then i am back to not understanding the message i got about calibrating displays, because i did quite a bit worse than 0.002.

edit: nerd-sniping myself a little bit. but it appears (stressing: i know nothing) the "0.02" is accurate, but calculated by showing someone two colors and asking "are these different" until the person answers the question correctly 50% of the time. which is a different question than "where, precisely, is the line between these two colors". with the different question, it ends up compressing the result down by about an order of magnitude.

Right. The average score is under different test conditions. Obviously this game is a little silly version with very little accuracy to the lab testing, but hopefully it gets people thinking about this stuff a bit more! Which given your investigations into this, I would say it has succeeded.

		I'm colorblind, but I ended up getting a 0.0028 "much better than average" score. Hmm... Fun site! To promote some further reading: OKLab isn't actually a perceptually uniform colorspace. It's better than others, but it was specifically chosen as a tradeoff between accuracy and speed (hence the name OK). When you start digging this deep, you quickly learn that we have yet to invent any perceptually uniform colorspaces; even the most precise models we have end up using fits and approximations. Color has some really inconvenient properties like depending strongly on brightness and background. Frankly, given the differences in human biology (having orders of magnitude differences in relative numbers of each cone, for instance), it's surprising we agree as much as we do! Human color perception is an endless pit of complexity. (Note, I don't say any of this to detract from what you've built here, merely expand. Your site is awesome and I love it!)
