Most punk hair styles incorporate at least minimal amounts of unusual hair colors or color combinations. The most obvious choices are unnatural colors: blue, pink, orange, green, and purple are popular punk colors, particularly in neon shades. The color may be applied to all the hair or just to sections, highlighting tips of strands, stripes, or particular parts of hair that will be elaborately styled such as the crown or bangs. Any radical color can be used in a punk style, including shades that have high contrast: platinum blonde tips on black hair, for example.
