Artists' Oil Colour is unmatched for its purity, quality and reliability - a success which is reflected in its world-wide reputation amongst professional artists. It has 120 colours in the range, offering the widest spectrum of all the Winsor & Newton oil ranges. Our quality standards include the use of single pigments wherever possible to create individual colours. Combined with strength of colour, single pigments provide a wide colour range in themselves and offer cleaner, brighter mixtures with an infinite range of hues. This is particularly important for greens, violets and oranges. Single pigment 'secondaries' considerably broaden the artists' available spectrum. There are 80 single pigment colours in the range.
