Matisse Iridescent medium MM24 will give a pearlescence or iridescence when mixed with Matisse colours, (especially those colours with transparent pigments)

This medium has been formulated to be either mixed with any of the Matisse range of colours or may be used in a wash over the top (more effective over dark colours).

This medium is based on pure iridescent pigment and contains no fillers or titanium dioxide; therefore the resultant mixes of iridescent colours are far more intense and richer in colour.
