I believe that The Lightning of RWBY (As i'm calling her for now) is based off Neopolitan Ice Cream. Take a look at it, the flavors of the ice cream are Vanilla, Chocolate, and Strawberry. Lightning of RWBY may fit this description because her hair is the color of Strawberrry and Vanilla, (i'm not sure if you can see the chocolate part.) Her name could be something off the Ice Cream name.

that's my guess.
