I need something like this:
I'm using SASS to create a parent theme that has say 10 child themes. Those child themes simply vary in color and BG texture. So I have a couple variables set for a primary color, secondary color and tertiary color. All shades and variations are done in the original theme via color functions off one of those colors.
So for instance, I need a BG shade slightly different from the primary color - and I have what the original design calls for, so I'm basically looking for the algorithm that generates the color difference between those two - i.e. my request.
Is there a tool like this?
