Anime Fanfiction Rant book

HAIR COLOURS

I have now realized the truth and the truth is that all of OC's have either one of two hair colors :

FLAMING RED HAIR

OR

RAVEN

Now let's get down to business
RAVEN is NOT BLACK IT IS A VERY DARK BROWN. IT IS NOT BLACK OKAY.

There now wasn't so hard was it.

In the anime world where you can give your OC hair colors of the rainbow we always want to stick with red hair can someone please tell me why?????
And then not only is her hair red its flaming red. Well let me tell you something not all of us can have hair the color of blood. Realistically speaking no one has hair naturally that color.
Does your OC kills people and dip her hair in their blood to get that crimson hair.
Maybe.
Probably.
No.
Your OC is not a vampire even so you cannot I repeat cannot have characters like this is it so hard to ask for a character that has blonde hair or maybe brown hair...any other hair color.
Where are my purple and neon green haired people.

WAIT FORGET THAT I SAID THAT WE DONT NEED SOME SORT OF HOT PINK HAIRED GIRL IN ATTACK ON TITAN
