Suggestion: Incorporate background color and WCAG contrast annotations.

Useful for designing against a background color.

Hello @flowchartsman. This is a good suggestion but unfortunately well beyond my understanding of color arithmetics. I guess this can be achieved by campling the color space given to the algorithm, like it is done on the website for dark background palettes. One thing to keep in mind is that in some scenario, some parameters of the algorithms may prevent fast convergence if the color space is too restricted.
