As an artist and a painter, Michael strives to create colors that are true, vibrant and pure. The greater the pigment load, the greater the resistance to fading. Michael Harding colors are made without fillers or extenders. All colors, except as indicated are ground in a grade of refined cold pressed linseed oil chosen for its neutral acidity.
