The popular natural stone called granite, gets most of it’s color due to an abundance in one specific mineral. For example, pink and white granites tend to have more pinkish orthoclase and microcline over plagioclase. White granites tend to have more aplitic plagioclase, yet have some dark mica and hornblende too. Basically, these other minerals are different colors and their combination along with the color and size of quartz and silica make up the designation (and general color) of the granite.
