Old Holland Watercolour (18ml)(Raw Umber)

One of the unique characteristics of these watercolours is the unparalleled colour strength (maximum pigmentation). And while this high colour strength requires a slightly different approach on the part of the aquarellist (so little paint is needed from the tube or cup for the desired colour effect that you have to get used to the ratio of paint to diluent), the advantages are clear. Pigment classification: Natural iron-Manganese oxide Colour index: PBR7 Colour index number: 77492-77491-77499 Lightfastness: Lightfast pigment according to ASTM Category 1 and 2 Opacity/transparency: Semi-transparent
