Inspired by a picture by Gregorio Vardanega and my perpetual interest in color.[br][br]The squares are colored by hue, 0 to 1, up to the number c. (Mod(i,c)/(c+1)) The circle colors are from the function colors(x), applied to the index i then the same modular function.[br][br]Shuffle mixes both lists and remixes each click. You can zoom in and out to get more or fewer. But it will only color the first 150!
