Winsor & Newton Artists' Oil Colour 37ml Cobalt Blue Deep
Winsor & Newton Artists' Oil Colour Cobalt Blue Deep is darker red shade of the semi-transparent clean blue pigment that is Cobalt Blue. It is mixed with linseed/safflower oil and is an extremely permanent color with very good lightfastness. It was discovered in 1802 by French chemist Louis Thenard as an alternative pigment to the expensive Lapis Lazuli blue pigment.
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.
