We use only the purest of pigments ensuring the cleanest, brightest colours, which in turn produce the best colour mixtures. Viscosity/Consistency: The buttery consistency of Artists Oil Colour, together with the smell of linseed oil, are the two characteristics most admired by oil painters. These qualities are unbeaten by other media. The stiff consistency of Winsor & Newton colours can retain brush or palette knife marks or it can be thinned to the very finest of glazes. Drying Times: The long drying time of Artists Oil Colour is also a key feature of oil painting. The colour remains soft and wet for a few days and therefore allows corrections to be made from day to day. All colours will become touch dry in thin films in 2-14 days. The different reaction of each pigment when mixed with oil results in the different dry rates. Each colour is individually formulated to optimize its drying rate, which helps artists to avoid the problems of slow drying under layers.
