Lascaux Sirius Acrylic Paints are high quality luminous acrylics with excellent lightfastness and a smooth, buttery consistency. Designed to maintain the purity of color when mixing, they are made from pure, lightfast pigments in an age-resistant acrylic-modified binder. They have a deep matte and water-resistant finish and are suitable for all porous supports.

The Lascaux Sirius Primary System is based on five primaries instead of the usual three. These are: Magenta, Red, Yellow, Cyan, and Ultramarine plus Black and White. The full range of colors can be mixed with ease and precision. Mixed in equal parts, the five primaries produce a neutral and vibrant black. Warm and cool tones can be defined logically since on either side a red and a blue can be differentiated.

The Sirius Primary System can be used in professions where the perceptual and sensual quality of color is essential: Fine Art and Design, Architectural and Interior Design, Color Theory, Art Education Classes, and Art Therapy.
