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 colours 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 colour is essential: Fine Art and Design, Architectural and Interior Design, Colour Theory, Art Education Classes and Art Therapy.
The specific advantages are:
* The System is easily used in practice, making it ideal for introductory courses, in schools and academies. A balanced colour wheel can be intermixed, creating the entire spectrum with only a few hues.
* When adjusting the lightness and darkness of a hue, the colour s intensity and consistency remain intact. Within the system, a wide range of subtle, vibrant and neutral greys can be mixed.
