Van Gogh watercolour is formulated to deliver reliable transparency and luminosity, with quality pigments that dilute evenly and produce clean washes. Colours are available in 10 ml tubes for artists who want to build their palette colour by colour, and in 40 ml tubes for shades used more frequently. The range is divided into two series: Series 1 groups classic colours based on common pigments, available at a lower price point; Series 2 includes colours with rarer pigments or special effects, notably the metallic and interference shades that produce shifting reflections depending on the angle of light. Pan sets allow for starting with a balanced selection, from the compact 12-pan format for outdoor work to the 48-pan set for a complete studio palette. For the full Van Gogh range, visit Van Gogh.
