W&N Medium Watercolour Granulation Medium 75ml

W&N Med OMV 75ML Granulation Medium
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.
Always work with painting horizontal.
