I try to make one character stand out from the norm, usually the main character. Baul and Isador (twins) were always bright hair and very different cloths compared to the normal dress everyone else was wearing. It's because they are the odd ones in the setting. Gavin, the man lead was a t-shirt and jeans guy.

In my new comics Spec5, the main character has white hair, unlike everyone else that has normal hair colors.
