Raw Sienna is a bright brown pigment. One of the oldest pigments, it can be found in prehistoric cave art. It is named after Siena, Italy where the pigment was sourced during the Renaissance. 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 works pace or don’t want solvents in school or at home. We make Artisan Water Mixable Oil Color 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.
