Professional Water Colour Techniques: Three Contributors to Granulation
Many artists lean towards water colour for its ability to convey a granulated aesthetic when applied consciously. As a natural property of certain water colours, granulation causes the pigment within the paint to settle outside of the binder, clinging on to the valleys of textured water colour paper. If you’re painting a foggy or cloudy scene, or portraying the haze of beach waves, this can be a particularly useful technique to employ.
The more water you use when mixing your water colours together, the more intense the granulation effect. Winsor & Newton Granulation Medium will enhance the granulation effect, as shown in the test at left by artist Debbie Bryan.
Using Sepia, an opaque, non-granulating colour on cold pressed paper, she shows the difference between using plain water and Granulation Medium. The example reflects the contrast between:

Rough surfaced papers leave much stronger granulated effects, as the pigment clings on to the texture of a granulation-friendly surface, like our Cotman Water Colour Paper Pads.
Debbie Bryan also ran a test of Professional Water Colour Cobalt Violet (see: example at right), a naturally granulating pigment. Applying the paint to rough, not/cold pressed and hot pressed smooth paper, she shows that although certain pigments are likely to give a granulated effect on any paper, the roughness will exaggerate the granulation.
