Again: A Color Wheel.

I am probably one of the very few people who didn't like the colour wheel. It limited the type of textures used on an object to seamless patterns and then some of those seamless patterns were a bit blurry or not so seamless. It was also slow to load when recolouring, and also during gameplay when moving the camera and going from place to place. Maybe they could release a program that allowed for easy recolouring of objects and CAS items outside the game. They had one for TS2 CAS.
