A low- viscosity formula, that increases the granulation of colour, giving a natural 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.
