I did just now. Honestly, it's... okay. I actually feel that g=8 d=c=2 
s=256 works better. (Can play with the step count, main point is 
limiting the grid to 7 or 8 with 2px dots instead of single pixels.)

Is green even a possible color? Is it just coincidence I am only getting 
red - blue? I was thinking that was intentional, as it avoids problems 
in case of persons with partial color vision. (Personally I wouldn't 
mind seeing greens also, but if you use full spectrum, for a11y you 
really need an option somehow to limit to only two opposing hues.)
