Beach sand color is one of important components of coastal landscape. But color information has not been used to coastal engineering. Color determination of sand grains collected in 164 coastal sand beaches was performed with a scanner and the relative frequency of sand color was calculated based on RGB color palette. The principle component analysis and cluster analysis were applied to the relative frequency of sand color. The sand beaches were classified into two general groups; gray and brown. The artificial beach is consisted of many colored grains. Tan and brown colored grains are seen at singing sand beaches. Sand color changes are confirmed before and after the tsunami which has attacked the beach in Japan last year.
