The article describes the optimal composition of color compositions that give a stable color of cotton fabric by forming metal complexes containing a salt of a polyvalent metal of sodium nitrite and secondary phenols in the structure of a cotton fiber. In our compositions containing iron (III) sulfate or nickel (II) chloride, the ratio of the ingredients is 1: 1, and adding a ratio of 1: 1: 2 to the composition mixture of cobalt (II) chloride, and with copper (II) sulfate, - 1: 5: 7.5.
