Not entirely sure temporary tattoos would be ideal for limb gradients ahaha. At that point, might as well just spray paint myself!
That's what I was proposing though. That's why I'm confused about people bringing up tattoos. They just added a weird wrinkle to it.Why didn't you just avoid the whole pain/effort argument by just suggesting giving someone an instant, painless change of color? Like you have the power as the one posing this hypothetical to do so.
Anyway, I think maybe having speckled skin like a deer would be neat.
