So i need hair color advice?

i have pretty dark-medium brown hair





ive died my hair a few times, and im going to get it dyed and cut soon. im sure on the cut but not on the colr! i need help! i have hazel eyes and pretty fair skin i get tan in the summer though(im part mexican) but you cant really tell i dont have the real dark eyes and skin like my dads side, so i dont know what color for my hair. all my sisters are fair skinned and blonde(bleach blonde) because they have a different dad, therefor theres none with my exact skintone to tell me what color to do! so please help! im going to wnat highlights in whatever color i choose so if you could also help with that, it would help thanx

it's kind of hard to judge without a picture, but i think a dark auburn-y color would look pretty.(: especially with some dark blonde and brown highlights.
