How much leeway do we have with color palette? For example, AK letters are Green, Brown, Pale Yellow. But I was thinking about doing my letters for different attractions (like Nemo, Tough to Be a Bug, Dinosaur, etc) and those attractions may or may not fit into that color palette. I was thinking about using at least one of those colors so something would match, like a shadow layer(s). But the top layer color or pattern may not. Is that okay?
