I'd say gender politics aside, I just don't think the color pink works as well on the male form as it does on a female. However, a bit more variety with regards to what positions female heroes have on the team and what their hero-colors are would be good all around. Including of course, changing things up now and again with a female Red.
Save pink for a female character whom that might best fit rather than having it be a lock that if there are two females on a 5 member team they only get pink and yellow. Throw white and purple into the mix more often for the 4th and 5th. Those two colors are a bit more versatile and IMO could be applied to male or female heroes more easily.
