Old Holland Classic Oil Colors are produced according to the traditional recipes that were used in 17th century to create colors in that have retained their clarity to this day. Only the best pigments and binders are used to produce this very concentrated and light-fast paint, which results in higher color strength, hiding power, and intensity. Only cold-pressed linseed oil from the first pressing is used for the binder. This optimizes the drying, promotes its permanence, and increases the flow of brush strokes. Every Old Holland Classic tube label displays its contents on an actual paint color strip, so each tube is its own color card.
