Artisan Water Mixable Oil Colour has been specifically developed to appear and work just like conventional oil colour. The key difference between Artisan and conventional oils is its ability to thin and clean up with water. Hazardous solvents are not necessary for Artisan and artists can enjoy a safer painting environment, making it ideal for artists who share a work space, schools or painting at home. Like traditional oil colour, Artisan Water Mixable Oil Colour is made from linseed oil and safflower oil but the difference is the linseed oil and safflower oil used in Artisan have been modified so that they will mix and clean up with water. Permanent Rose is a bright rose violet colour. It is a transparent quinacridone pigment and was introduced in the Winsor & Newton range in the 1950s.
