Each watercolor has so much pigment the tubes must be filled by hand!
Old Holland Classic Watercolors are super intense colors made from extremely concentrated formulas. Old Holland, a leader in quality oil colors, has emerged as a quality leader in watercolor. Old Holland spent ten years assembling a range of 168 light-fast watercolors with the maximum degree of pigmentation that could be achieved.
For good transparency, a binder was formulated based on distilled water in which bleached gum types, pure glycerine (99.9%), natural sugar syrups, honey, rabbit skin glue and seaweed extract are dissolved. The color packs the greatest punch of any existing brand and is totally reliable with ASTM 1 or 2 lightfast ratings. Due to its highly concentrated nature, each color has an unsurpassed tonal range.
