Geometry Overlay for Palettes / Harmonies

[torridgristle]

Just recently I tried to do a triad color palette but I was having trouble figuring out where it would be on the plot. In Paletton you can see an overlay of moving dots showing the geometric relationship between hues you have selected, this would be useful. Either something just like Paletton where it's dots what move around and you can adjust the angles and it stays symmetrical or something else what provides the same data to the user.
