I notice that in Ranma 1/2, certain characters
always seem to have a blob of white in their hair.
Someone pointed out to me that it indicated a color
other than black, but even Mousse has that white
blob on him.

On the cover of several of the comic books I have,
Ranma (with red hair) still has a white splash on
her head, indicating a "light glint."  But then
why doesn't Akane's hair have that same glint? 
Why does Ranma-chan have it and Ranma doesn't?
How come both Shampoo AND Mousse have it?

What the heck IS that white splash?
