Media Interference Fluid Acrylics include six translucent colours that shift in colour and appearance depending upon the light, viewing angle and colour of the surface on which they are applied.

When applied over a dark colour you will see more opalescent colour and less of the colour shift. When applied over a light colour you will see a sheer opalescent colour but more of the colour shift. Thin applications in a wash or glaze increase the visual interference effects.
