Wonderful design. Example images are an awesome touch, quite useful!

Feedback for mobile safari - it would be helpful if the wheel was fixed to the top of the window (position:sticky?). Not the end of the world to scroll, but there’s quite a bit of back and forth as-is.

This is really neat.

One suggestion, make the two circles in the color wheel that you can drag slightly different (at least). Maybe just line thickness, shape, filled/open something to note that dragging one will produce the opposite results from the other. Maybe make only one of them draggable?

I know it doesn't really work this way, but I only figured out by accident that dragging to the orange/blue vs blue/orange produced totally different results.

I like many things about it, but I think having it default to a red-green complimentary combo is a little iffy. Those of us who are colorblind (and we're 12% of the male population, and 0.5% of the female!) will have a lot of trouble seeing it clearly. Maybe just have it start on square instead? Or maybe have the line start out horizontally between blue and orange instead of vertically between red and green?

Offtopic, but why is there such a disparity in the percentage of colour blind people between the male and the female population?

"It is sex-linked: genetic red-green color blindness affects males much more often than females, because the genes for the red and green color receptors are located on the X chromosome, of which males have only one and females have two. Females (XX) are red-green color blind only if both their X chromosomes are defective with a similar deficiency, whereas males (XY) are color blind if their single X chromosome is defective.[12]"

Color blindness is due to a defective gen that express one of the three kind of cones in the eye. Usually the cones more sensitive to middle length photons (M ~green) become closer to the cones more sensitive to long length photos (L ~red) and thus they can only discriminate colors in between thanks to the other short length cone (S ~blue), but the S cones are almost blind to these colors.

The thing is, these genes are in XY chromosome in males, and thus we only have a single copy for each of these genes. Women have two copies of each gene, so even if one goes wrong, the remaining one can express the cones.

Funny thing is woman with a defective gen usually just goes unnoticed, but the defective gen in some cases can express a fourth kind of cone with a peak sensitivity between M and L cones, allowing them to perceive colors that usual humans can't perceive.
