The current identity (5) cannot ColorMap (lacking permission 3)

I was researching this myself as I was making a livery select ui for a game I was working on and found out from the Roblox API reference site that the ColorMap cannot be changed with scripts. (Only the command because thats apparently useful) Source below SurfaceAppearance.ColorMap (roblox.com)
