I would buy multiples of a stone floor in Grayskull green for the Mondo figs.
I was gonna do this one in Grayskull green but didn’t have anything on hand to mix that color up. I’ll have to check on the purple. Problem is, because of the paint I use, I have to get custom colors by the gallon so I’d have to get a bunch of preorders going before it’s worth doing a special color like that.
