The most costly component of any paint is the pigment. Each colour is made up of one or more pigments, coming from a staggering variety of sources. Each of those pigments in turn has gone through a variety of manufacturing processes in order to become a compatible component of the paint. The difference in price reflects the pigment or pigments used and the amount of processing required.
