I feel like the two people that posted don't know about the colour naming rule

Regem is a biblical name meaning purple, Dewitt means "The White" in Dutch so that fits with the color naming convention of Rwby~ Regem's color is purple and white but if I have to give him a specific color it would be Violet~

Also with Rwby color naming doesn't have to directly mean a color as it could relate to a color which is what I'm guessing what Ninja did as Aiden means little fire which could relate to red or orange or even yellow. And Himura in japanese is Scarlet Village so I'm guessing his color is red or more specifically scarlet
