Abstract
The present disclosure provides a coating composition comprising a pigment in the color space L* from +26.00 to +34.00; a* from −1.00 to +3.00; and b* from +1.00 to +5.00, as measured using the CIEL*a*b*DE* system, where the amount of reactive manganese oxide is less than 0.1 atomic percent (At %) of the pigment. The present disclosure further provides a method of making the coating composition.
