Granulation in watercolours is an outcome exactly where alternatively of a sleek location of colour, the pigment particles settle out and produce a speckled visual appeal. When watercolour pigments ‘granulate’, they kind compact dots and/or teams of flakes that are visually obvious. Some colors have a all-natural inclination to granulate extra than other individuals, and watercolourists occasionally choose advantage of them to include texture. There are mediums that can be extra to raise granulation.

Floor

Watercolour grounds are acrylic-primarily based primers built to present a appropriate total of absorbency to a surface, so that it is all set for watercolour to be utilized. For case in point, they can be utilized to adapt any universally primed canvas for watercolour portray.

The most textured paper offered – it is pressed in between sheets of textured felt throughout the drying system and is not pressed involving easy rollers. The heavier textured floor signifies that granulating results are increased.

One Pigment Colors
