I have had my hair every color imaginable, and in my opinion pink highlights look good with just about every color except for brown. My hair was light brown when I decided to get pink bangs, and let me just tell you they were terrible! I hated the way they looked especially when the color started fading, so I recommend you dye your hair a darker color before going with a color like light pink. I did this, and the difference was spectacular! I don't know if your getting it dyed or the extensions put it, so just remember that light and dark colors mix well because of the contrast ,but light-light/dark-dark colors tend too lose themselves in one another. This is where extensions come in handy to experiment, so if they don't look like what you wanted, you can just take them out.
*skin tone also plays in with the hair color
* wardrobe scheme really doesn't matter to most but something to think about if you want your hair to go well with your look
if you have to ask then don't do it, plus its not a good look. Plus you have to bleach it first cause if you put pink in the hair color you currently have it will be more of a peachy color. If you wanna try it, then buy a couple of small clip on extension pieces and clip it on, then you got the right color and you can take it out when you are tired of it
