I've been using Nova Color Paint since 1999, after working with a mural artist from Los Angeles, CA. Their paint is of the highest quality pigments and acrylic binder. It's fluid, but not too fluid, and works perfectly with my glazing technique. Their matte medium and varnish applies easily and is long-lasting.
The best part is that their paint and mediums are about 1/2 the price of what you pay at your local art store!
If you use my affiliate link below, you will pay the same price as what you pay at their website. But a small portion of your purchase will directly help support what I do at Realistic Acrylic Portrait School—creating amazing videos, tutorials and classes for students and portrait artists. How cool is that? Win-win!
