Better color cycling for wallpaper

[DustinBrett]

I'd like to have a better and brighter rainbow of colors. Both seem possible.

Although now I am wondering what kind of support I have on the three.js/canvas side for these color gamuts. Hard to tell, this will be interesting anyway. I might consider doing fallback colors for other things if I can make it look nicer. I have been reading all source colors as RGB always but maybe some of the stuff I took colors of actually had a p3/rec2020 color, I will look into that also.
