M Graham believes they are responsible to every artist who chooses their colour. Their watercolour is made with a time-honoured binding medium of natural blackberry honey and pure gum arabic, which give it extraordinary strength that is easily diluted for smooth, controlled washes and richer colour. Honey absorbs moisture from the air, preventing hardening on the palette or in the tube.

Graham paint set, the "Desert Southwest" Watercolour 5 piece set. The colours are brilliant, highly pigmented and suitable for all traditional techniques with beautiful, even washes and no hard outlines.

The set contains High Desert Red (Quinacridone Rust), Desert Floor (Yellow Ochre), Talavera Ceramic Yellow (Indian Yellow), Sunset Violet (Mineral Violet), and Jewel of the West (Turquoise).
