FIELD: production of pigments comprising chromium oxide. SUBSTANCE: method involves heat decomposition of chromium anhydride. The process takes place in the presence of modifying additive, its quantity being 10-1000 % of mass of chromium anhydride. Sapropel is used as mentioned above modifying additive. Desired pigment has high anticorrosive properties. EFFECT: improved efficiency of the method. 2 tbl
