Thanks everyone for all the support, comments, and letting me know about some bugs! One of the biggest challenges I had was finding an algorithm to determine the "difference" between two hex codes. Anyone have any tips on that?

Hey I've done similar games! check http://color.method.ac. You need to convert hex to CIELab, and then apply a color difference formula http://en.wikipedia.org/wiki/Color_difference

Don't let the complex versions put you down, the simplest formula is good enough, just Math.sqrt( Math.pow(L1-L2, 2) + Math.pow(a1-a2, 2) + Math.pow(b1-b2, 2) ).

Awesome, thanks for the advice. We were looking into alternatives for algorithms that better reflected human color interpretation, and that looks very helpful. And yeah, your games are awesome, we basically modeled this as "the Kerning Game/Color Game, but for brands."

Thanks a bunch there! Will definitely look into that formula, you have made some AWESOME games as well :)

(Can't wait for Method of Action, by the way, looks awesome and could be seriously helpful for me.)

Are you allowed to use these logos for this purpose?
