This increases the granulation of colour, giving a mottled appearance to colours which usually give a smooth wash (e.g. Winsor Blue), or enhancing the effect of granulating colours (e.g. French Ultramarine).
For maximum effect dilute colour generously with medium alone.
This medium gives pearlescent or glitter effects to water colours and is particularly effective when mixed with transparent colours especially over dark backgrounds.
Mix with transparent water colour or apply over a dried wash.
Shake well before use.
