Granulating Colors

Top Granulating Colors in Your Set

• Ultramarine (PB29): This is the strongest granulating color in the set. It is a traditional mineral pigment known for its heavy particles that naturally create texture.

• Burnt Umber (PBr7/PY42): Traditional "earth" colors like this often exhibit mild granulation, though it is less dramatic than Ultramarine.

• Burnt Sienna (PR101): Similar to Burnt Umber, this earth-based pigment can show a slight grainy texture, especially when used in heavy washes.

• Yellow Ochre (PY42): While an earth color, the synthetic version used in the Cotman range is often more uniform and generally rated as non-granulating by Winsor & Newton.

Why Other Colors Don't Granulate

Most other colors in this set, such as Lemon Yellow Hue, Cadmium Red Pale Hue, and Viridian Hue, are "Hue" versions made from modern synthetic organic pigments. These pigments have much finer particles that stay suspended in water, resulting in a smooth, uniform wash rather than a textured one.
