Gamblin 1980 Oils - Naphthol Red PR112 Naphthol Red AS-D

Gamblin’s approach is different. 1980 colours contain pure pigments, the finest refined linseed oil, and marble dust (calcium carbonate). Since oil painting began, these three ingredients have made more affordable colours.

Painters experience true colours without homogenized texture or muddy colour mixtures. Gamblin's approach to using traditional raw materials and processes ensures that artists experience the luscious working properties they expect from their oil colours.

Naphthol Red: Modern organic, warm red that closely matches Cadmium Red Medium in masstone. It makes more intense tints more transparent. Excellent for high-key painting.
