Van Gogh acrylic colours are made with high-quality pigments under superior Dutch quality standards. The paint can be used straight from the metal tube, or thinned with water. Due to the short dry time, it is easy to paint layer upon layer quickly. The heavy-body paint has high pigment load for strong, intense colours for working with artist paint brush or palette knife. These student-artist grade acrylics have lightfastness ratings of good (25-100 years under museum conditions) to excellent (100+ years under museum conditions).
