Not sure about the use for it, is it supposed to be design or painting?

I've thought about making this for a long time to help me with painting, but in that case I think to be useful you need a bit more ways to see the data -- mostly, the thing that is the most important is value. So to get something useful out of it you need a distribution of the hues conditioned value.

And for design, the problem is a bit different. You may have a good looking palette, but 'inverting it' for dark mode is not trivial, and neither are gradients, getting intermediate colors, or getting a shifted hue.

It's called inspiration so it's fulfilling its promise, I'm just curious what are your thoughts on these since you obviously thought a lot about it.
