Michael Harding Deep Purple (Dioxazine) - Deep Purple has tremendous use in all aspects of painting but should be used with caution by new artists as it has a tint power only matched by the Phthalocyanines. However, please do not be daunted by this description as when combined with whites it produces remarkable shades. Also, its slight addition to transparent yellows, such as Indian Yellow, can result in some extraordinary results that one can only describe as dark yellow which as a concept can be a little strange.
