This medium-to-dark warm reddish-blue is highly lightfast and of medium tinting strength.

Its sedimentary quality increases its versatility. Mixed with various proportions of other blues, French Ultramarine is a wonderful sky pigment.

Modify it with Quinacridone Gold for delightful greens that remain colour-coordinated. Mix French Ultramarine with Quinacridone Burnt Orange and be rewarded with an amazing range of blue to brown grays. Mixed with either Quinacridone Rose or Pink, a range of purples result. For another important mix, see Hooker's and Sap Green.
