Two Thin Coats shadow paints are the darker tones in a triad-based paint system designed for shading or as a base layer to build up brighter midtones and highlights. This colour can be used in conjunction with the triad system or is a great colour on its own. Two Thin Coats paints deliver rich colours, smooth coverage, and effortless blending, formulated for smooth and easy-to-use painting. These paints are all water-based acrylics.
