What color highlight shoud I dye in my hair?

Pink. Or any color that extentuates your skin tone. A dark red or maroon would be good.

I do think blue would be really cool because it would bring out the blue in your eyes. Or pink. Just NOT green! That always looks bad in dirty blond hair! I learned the hard way! Good luck and have fun with it.

Oh, that sounds delightful. You could change it from time to time, just for fun. I suggest a nice neon blue to start.

I’ll go with the pink too. Blue, although it will match your eyes, seems like an odd, clashing color for your hair color. If you had black hair, then I would say blue would be great. So I’m going with fuschia pink or watermelon red.

Wow, you guys have great advice! Thanks!

I think the blue will be more compatible.

It is generally recommended to transition a shade slightly lighter or darker than your natural hair color. Since your hair is dirty blonde, i recommend you either bleach it to a light shade of blonde or dye it to a darker shade like auburn.
