The invention discloses a colorized reflection heat insulation coating. Carbon black, iron oxide red, organic yellow, phthalocyanine green, phthalocyanine blue, and other conventional common pigments are replaced by the pigments, namely nickel iron chromite black, nickel iron chromite red, cobalt blue, titanium yellow and cobalt green, so that the colorized reflection heat insulation coating can meet the demand of the external wall decoration on colors and has high reflectivity to solar energy and a good heat insulation effect. The invention also provides a color card by which a colorized coating is formed by mixing the nickel iron chromite black, the nickel iron chromite red, the cobalt blue, the titanium yellow and the cobalt green, a user can quickly mix the coating of the corresponding colors according to the pigment formula corresponding to each color in the color card, and the color card is convenient to use.
