Actually, if you look at a few good pictures, it is ridiculously easy to tell a mojave or a cinnamon from a normal.
Notwithstanding the color differences, the patterns are nothing alike. I have never seen a mojave with a normals pattern or vise versa. The same goes for cinnamon. Normals always have "alien heads" that connect to the belly. Usually in wide bands. Mojaves and cinnamon's have " alien heads " that float separately from the belly, or are only connected by a thin line.
So even without the colors, you can easily tell them apart.
