Well, I'm wondering if it is is possible to modify chargrp or something (if that is the right file) to make it so that there are more choices of hair colors. Like if Dark Elf hair color stops at D, how can I make it so it goes on to E with the custom color? I hope you can understand what I am trying to say...

you mean insert more than 3 o 4 colors ? don't remember original values of hair when create character.

I think that this is impossible without java part, because if you see the delf with blonde hair with your modified patch the others with the normal patch will crash, or their client wont read the E hair color of the delf because theu are limited to D for ex. I think that this need java work

he can do it adding item like new accessory, is not the same but well is 1 way I know.
