| SCM toolkit and GU edit both do this. SCM draft also has a limited color change thing, but with the other ones you can do 1-255. the player colors of what to change them to (accurately) are in the FAQ sticky.
SCM toolkit has a tutorial to set it up somewhere here if u want to use it, it's a bitch. but GU edit, even though I think is a bit worse, is much easier to set up |
