Different Colors with every Object

Hi, for my first game i wanted to create a simple enviroment of Containers for the player to walk in.
I made a Container + Texture in Blender and got them setup so i can use it, but now i want to place more containers and have the Color of them Change (aswell as modify the uv projection but thats not THAT important) with each Container i place.
Like i said this is my very first Project and it took me 2 days to just implement my walking animation so please be patient with me. :smiley:
