bot colors

Maybe it is just me but I am having a hard time telling what color an army is.  I think the problem is that you are only change part of a bot with the color that you select.  I think the whole unit needs to be the color that you picked.  I am finding it very very hard to distinguish what bot belongs to what army because I can't tell what color it is.  Does turning on health bars make a differences?  How are you dealing with this issue?
