A colourant (British spelling) or colorant (American spelling) is something added to something else to cause it to have a different colour. Most colourants can be classified as, or as containing, dyes, pigments, or some combination of these.

Colourants (or their colourant ingredients) can also be categorized by their chemical classification, such as inorganic (often from a mineral source) and organic (often from a biological source).

Colourants can be used for many purposes including printing or painting on a substrate surface, and for colouring many types of materials such as foods and plastics.

Paints and inks are colourants that are themselves usually made from pigment and/or and dye colourants, along with binders, fillers and additional components.
