Dr. Ph. Martin’s Radiant Concentrated Watercolours

These transparent colours are produced in an extremely concentrated form to achieve the greatest possible brilliance. Use directly from the bottle or dilute with water. Dr. Ph. Martin’s colours are primarily formulated for graphic arts work on paper surfaces intended for reproduction, and are especially popular for airbrushing. Like all aniline dye base colours, they are fugitive when exposed to direct sunlight over time.
