My 2cents

I'd go into why 3 alliances will NOT work, but I've done that too many times in the last couple months.

I will leave you with this: The last time they did 1v1v1, the colors were red, blue, and white, with white removed for eliminations. White numbers on white bumpers would be easily solved by requiring a black border on all numbers.

The last time they did more than 3 separate scoring opportunities for robots, in 2001, the 4 colors were red, blue, green, and yellow.
