I've been play with an trying to understand the settings here but with little luck. Anyone have some good guidance on how to configure these usefully?

thanks

Yeah I hope we can get to be able to set presets for that and stuff! From what I understand, h s and v stand for hue, saturation and value, respectively.

Playing with values, changing Shift will change the entire gradient bar thing, so if I set all delta to 0 and shift to max (max being 1 and min -1) it loops back around to a really saturated bright red. 0.5 hue will get me cyan (opposite red on color wheel) so it appears hue loops back twice. -1.0, 0, and 1.0 are all red hue. For saturation it's from unsaturated (-1.0) to super saturated (1.0). Value affects lightness from black (-1) to normal to white (1.0)

Delta changes the gradient from the center. So if the starting (shift is all 0) is red the middle value is red and shifts to left and right. Higher h means more colors in the gradient. And at negative value it gives you a flipped version. Etc for value and saturation.

I hope my explanation wasnt too confusing! Just ask questions if it is

Great explanation. Between your answer and some more experimentation I think I get it now. It's actually a pretty cool feature

Thanks for the help
