Currently, we only publish the pigment and lightfast information for Dr. Ph. Martin's Hydrus Fine Art Watercolor.

Unlike some more traditional products, many Dr. Ph. Martin's brand products contain multiple dyes or pigments—sometimes six or more colorants. Pigment information for Synchromatic Transparent, Radiant Concentrated, Bombay India Inks, Spectralite Liquid Acrylics, Iridescent Calligraphy Colors, and TECH Drawing Inks is held as proprietary.
