So for example, if they are using three colors (let's say red, blue, green), they would need to select a primary color, a secondary color and an accent color. The primary color would be all headers, the secondary would be all links plus the sidebar border and the accent would be the link hover color and the sidebar backgrounds. (These are random, made up examples - that would probably be ugly). What would it take, generally speaking (but more specifically than "PHP") to make that happen on the admin side?
This is still pretty theoretical, I'm just curious. My PHP isn't amazing, but I can usually pick out solutions to specific problems in it.
Related: Might someone be willing to give me a hint as to how I could move many of the color settings to one tab and have them all use the color picker/ show the color like the link color fields do? I'm not asking you to do it for me, just give me a nudge in the right direction

Thanks & looking forward to learning/ theorizing/ discussing
