I use to put make up on my friends face, but i dont know which color should i apply?

How can I make my makeup look more natural? I have dark brown eyes, tan skin, and medium brown hair? Any tips on how to apply makeup so it can look natural?, like what colors of liners and blush should i use. Thanks :p

Sorry for the eyesore:

Anyway, I have pale pale skin and dark dark hair, it’s natural.
Before everyone’s all GO EASY ON THE EYELINER yes, I know. XD
I want to know what color lipsticks/Lipglosses, eyeshadows, eyeliners, and blushes would enhance my pale skin. I know pale skin is out or whatever, but I like my skin out it is.

I’ve never colored my hair in my life, so what color would suit me well, or should I just leave it black?

Thanks.
