Winsor & Newton Watercolor Medium, Granulation Medium, 75ml (2.5-oz) bottle

Winsor & Newton Water Colour Medium, Granulation Medium 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.
