Playing with Gradients. Yellow to Green, Yellow to Red, Magenta to Blue with 6 total stops on each one. The two end Hues are 100 % strength while the 4 stops between are the hues that take you from one side to the other. Then I added a texture effect to them to play around with. These are quite bright as I was playing with pure hues and not tints, shades or tones which would make them less YOWZA on the eyes. If I have time tomorrow I will try doing it from a photo. This is fun to play with.
