Winsor & Newton Winton Oil Colouris a range of high-quality oils combining the best raw materials and most advanced technology with the best possible value. Created by Winsor & Newton, leading British colour-makers for over 180 years, it has been formulated to produce excellent results across the colour spectrum, with high permanence and lightfastness and good covering power and tinting strength. Single pigments are used except where to do so would be less affordable; the result is a range with a pigment load higher than many artists' ranges, exceptional for general use and ideal for working in large volume at the highest level. Sold in 37ml and 200ml tubes.
