Black and green pigments based on chromium–cobalt spinels

► Co(Co 2− x Cr x )O 4 powders with different chromium concentrations ( x = 0, 0.25 and 1) were prepared by the polymeric precursor method. ► Co(CoCr)O 4 and Co(Co 1.75Cr 0.25)O 4 displayed a dark color and CoCr 2O 4 was green. ► The colors were related to the different oxidation states of Cr and Co...
