Winsor & Newton Artisan Water Mixable Oil Colour is a genuine oil colour made from modified linseed oil and modified safflower oil. This modification means Artisan Water Mixable Oil Colours can be used without hazardous solvents – they can be cleaned up with water. The colour has been formulated to appear and work just like conventional oil colour. The depth of colour, thick consistency, lightfastness, opacity/transparency, permanence and drying times are all comparable to conventional oils. They’re especially good for artists who share a workspace or don’t want solvents in school or at home.
