Griffin Alkyds are an artist quality range of colors that are compatible with, and work like, traditional oil colors, except they dry faster-generally workable for 4 to 6 hours and dry in 18 to 24 hours. This range includes colors made with high quality artists' pigments including genuine cadmiums, viridian and cobalt as well as various modern organic pigments. They have an easy buttery flow and exhibit consistent drying times with minimal yellowing yet more brilliance than oils. Color: Chromium Oxide , Size: 37ml Tube.
