Based on single pigment colors, this gouache is a professional's dream. Every color is dense, rich, and highly pigmented. No fillers, opacifiers, or adulterants alter the nature of the colors. Honey is added to gum arabic as a binder.
Color Swatch created using full strength/50/50 and was applied on cold press Bristol board (2 ply) material.
This Naphthol Red is an intense scarlet red pigment that is heavily staining. It has an average drying time. It is semi-transparent and has relatively poor covering power.
This Naphthol Red has been rated as having excellent lightfastness under ASTM testing, but other testing methods have demonstrated some tendancy for the color to fade with exposure to strong ultraviolet light. It has been considered a replacement for less lightfast naphthol reds such as PR3. Not suitable for exterior use.
Naphthol Reds are not considered toxic. Naphthol Red AS-D may cause eye, skin, or respiratory irritation. Contact with dry pigment should be avoided.
