As a general rule, dark and muted colours are the most flattering for black skin. This is because they help to create a slimming effect and can be very elegant and chic. If you want to make a statement, then brighter colours can look amazing on black skin, but it is important to choose the right shade.
For example, orange can look great on black skin, but a very bright orange may not be the most flattering. If you are unsure which colours suit you best, then it is always worth seeking out the advice of a stylist or colour analyst.
