Description
Standard Range
The Holbein Artists’ Gouache Standard range is available in 137 brilliant, predominantly opaque colours in 15 ml tubes. Colours are assigned to a series (A, B, C, D, E, and G), which reflects the relative cost and rarity of the pigments used. All colours are professional quality, with the series designation indicating pigment value rather than paint quality.
The range carries an overall ASTM Lightfastness Rating of A, with most colours classified as moderately durable (*). Opacity varies by colour; while the majority are opaque, some shades are classified as semi-opaque.
Certain colours contain ox gall, an animal-derived wetting agent traditionally obtained from cattle bile. Ox gall enhances the handling properties of the paint by:
• Improving wetting, allowing water to spread more evenly through the paint.
• Reducing surface tension, enabling smoother flow across the paper surface.
• Improving pigment dispersion, helping pigments remain evenly distributed.
• Enhancing coverage, particularly in opaque, metallic, and heavily pigmented colours.
• Aiding rewetting, allowing dried paint to reactivate more readily with water.
The presence of ox gall primarily affects the paint’s working properties and has little impact on the appearance of the finished artwork.
 Irodori Range
The Holbein Irodori Artist Gouache range showcases 48 authentic Japanese colours inspired by the landscapes, seasons, and natural beauty of Japan. Developed to the same exacting standards as Holbein’s celebrated Artists’ Gouache, the Irodori collection delivers outstanding professional performance.
