I love red hair, but it really depends on the girl. You said you have blonde chestnut hair, and sometimes that would look better, depending on the girl.

If you're coloring is fair then you may be able to have your hair professionally colored. Talk to your colorist about what shade to do.
But nothing is worse than a woman with noticeably colored red hair that she's trying to pull off as natural.
I have natural red hair- I'm a level 7 but I colored my hair and it was horrible and I know better as I did hair for years.
