To make sure that your hair colour looks good on you, you should choose a hair colour which goes well with your skin tone. Choose a colour that is either one or two shades lighter than or darker to your natural hair colour. Choosing a colour that befits the colour of your eyes is another way. If you have a warm undertone, then you must use warm colours such as copper, and if you have a cool undertone, then you should go for brighter colours like brown walnut.
