Artists are familiar with "simultaneous contrast," In which the background changes the perceived color. The circles in the illustration have the same CIE XYZ. It is not an optical illusion. It is a classical problem for Colorimetry color matching functions.

The recommendation for Munsell color pages is to use Munsell N5 (neutral grey with a value of 5). While the RGB values for N5 depends on the color space, it is an easy problem to solve. So that N5 doesn't disappear into the background, I use N5.5.

I am considering making the background a option as a way of demonstrating simultaneous contrast. When looking at a leaf for a specified hue, the background does make a perceptual difference. Any comments or ideas?

Some combinations have been known to cause photosensitive epileptic seizures especially if they're very dissonant and very bright. So I might say avoid a prototype that could conceivably do that. That's all I got oh master of color ❤️💚💙

Only Masters understand they are forever students. Deal with it! I wish my neurocognitive functioning were better because I'd love to dig in deeper with you on color topics but there's a point in my brain Taps out these days alas.
