Gouache I used unmixed colors so black white red red yellow and I used purple watercolor to tone the white paint to the shade I wanted it's water based paint with a chalky matte texture but it dries to be waterproof for the most part I might use a wax based sealant on it but it's holding pretty well
Hell yes!! I haven't used it in years, but I'd suspected because of the finish and how even the colour was. Never used a wax sealant before, it shouldn't change the colours, right?
I don't think so but even if it does this only took like 8 hours so I could totally recreate it but better if it affects anything
