Art Spectrum® Transparent Red Oxide complements the other two transparent oxides beautifully. A very deep top tone, with a strong reddish undertone, this colour also has exceptional tinting strength. Mix with other transparent earth colours to create a wonderful range, or with white for some lovely flesh tones.
