Black hair is like the best shade of hair one can have. Its a natural beauty in itself and any bright color that compliments black will go with it. There are a few things to consider before going on with every color though. Decide on the color to go with based on your haircut and personality, how better it might suit your style.
Burgundy , chestnut brown and purple streaks can never go wrong, though purple streaks is for the very bold. If you are a person who works for corporate, brown is the best option to go for, as it will go well with work wear and also look professional. If you are a fashion designer or freelancer, going in for the bold colors to match your fashionable outfits is the right choice. Try out small streaks or wigs with those colors to see if it goes well with your personality.
