Rotatable hue angle? #12
Description
Current colorscheme make sense if you remember ROYGBIV:
- R = positive real numbers
- Y = positive imaginary numbers
- G = negative real numbers
- B = negative imaginary numbers
but I could also see a mnemonic for G = positive and R = negative, due to G = Go and R = Stop, and similar to color scheme used in things like http://www.falstad.com/circuit/ or http://www.falstad.com/membrane/
