Winsor & Newton Artists' Oil Colour 37ml Indigo
Winsor & Newton Artists' Oil Colour Indigo is a transparent, deep blue pigment that can range from dark black to pale blue. It is mixed with linseed oil and is a permanent color with excellent lightfastness. Originally extracted from plants similar to blue woad used by the ancient Britons, it was synthesised in 1878 in Germany. It is one of the oldest blue pigments used universally.
Every tube of Artists' Oil Paint contains a calculated ratio of oil and pigment based on the quantity of oil in the tube. This varies from color to color because, just as some pigments need to be ground finer than others, they also need more, or less, oil to provide optimal performance.
Pigment Color Code: PB15 / PB29 / PBk7
