Following extensive consultations with professional artists, and a large number of tests in various countries, by the end of 2005, Old Holland had developed a range of 168 New Masters Classic Acrylics, consisting of opaque and transparent lightfast colours, free of any kind of additives and filler, with a maximum possible pigment content and a minimum colour difference between wet and dry paint. Responding to the current demand, Old Holland added an extensive selection of metallic, pearlescent, iridescent and interference colours, based on the same acrylic resin, and they demonstrate the same excellent lightfastness which has long been associated with the name. The result of the high dose of pigment and the patented binding system is that each colour displays the unique characteristics of the individual pigment. The paint dries to a satin gloss and can be used in a wide range of techniques, from thick impasto to ultra-thin glazing. A wide selection of multi-textured, matt, gloss, thickening and pearlescent mediums and additives were also developed to compliment the range of colour and increase the options available to the artist, both in imagination and development and in the final work.
