These magnificent paints are designed to look and work just like traditional oil paint, but they're a bit special. You can use them without hazardous solvents - they're happy being thinned down and cleaned up with water. They're especially good for artists who share a workspace or don't want solvents in school or at home. We make Artisan Water Mixable Oil Colour in 40 vibrant tones with a thick, buttery consistency so you can use them in a variety of ways. We've added a selection of special thinners, oils and mediums to this range, too.
