MACRO: Color Randomizer based on selected palette

Hey everyone,

I know this macro has to exist somewhere but I can't seem to find it.

I'm looking for a macro that allows you to pick a set of colors, let's say Orange and Black and will randomly fill selected objects on the page with those two colors.

I swear I've seen this macro before, but I've spent over two hours trying to find it and have come up empty handed LOL

Thanks!
