I've noticed that Rin and Emi are the only two girls...

...whose "name tags" do not match their hair color. In fact, Rin's name tag matches Emi's hair, and Emi's name tag matches Rin's hair. I wonder if that's on purpose, or just a random coincidence or a mix-up?

i remember reading about that on another thread................i think it was an accident i can't remember..........

I finally find someone else that thinks that too!

The color matches their personality.

Emi is Red, strong will and has so much vitality

Rin is Orange, unique and driven for her passion

Shizune is Blue, a commanding and vibrant color, just like herself

Hanako is Purple, Shrinking Violet anyone?

Lily is Yellow, pure and modest, yet has an underlaying playful side.

Its just coincidence that their personality color matches with their hair color, or that it is inversed in Emi and Rins case.

I also think that should be reversed.
