They were, then they became the "Rainbow Warriors", now I think they just go by "Warriors."
But if they go by the name “Warriors”, won’t that get them in trouble with the liberals upset about Indian themed nicknames?????

Prior to the year 2000, the University of Hawaiʻi's men's teams were all referred to as the Rainbow Warriors, complemented by an athletics logo featuring a rainbow. However, in a controversial marketing strategy over which many at the University and throughout Hawaii have misgivings [1], the school changed its athletics logo to a stylized "H" and allowed each team to pick its own team name.
This has led to the current situation, where the basketball, swimming and diving, and tennis teams have retained the team name of "Rainbow Warriors;" the baseball team adopted the name "Rainbows;" and the football, golf, and volleyball teams have adopted the name "Warriors."
