They allow darker mixes and a good range of browns and grays. They are semi-opaque pigments. Their drying times are quite short and have an improved grain size. In the Charbonnel color range only Raw Sepia has a natural iron oxide base. The synthetic oxides possess the characteristics of the natural oxides without their defects. They are more lively less grainy and dry more rapidly. They are also semi-opaque. The average drying time for Charbonnel earth tones is approximately 5 days.
