I suppose the trade off for not having those colors available for teams is that the field won't be colored mustard yellow, or any other hideous shades. Besides the RGB spectrum is big, can't we all just share nicely
.
Once we get a robot running though, i guess my team will have to see how the colors interfere. My teams shirts a shade of red not that far from what is used. If enough of us clump together in the stands, some robots might do funny things.
