## Long description

SMARTMAX Cotman watercolour in a 21 ml tube — Prussian Blue (shade 538) — is a transparent, water-based artist paint formulated for mixing, glazing and washes. The single-tube format provides controlled dispensing and convenient portability for studio work, plein air sketching and travel. This Cotman series paint offers consistent flow and reliable tinting strength suitable for studies, sketches and finished watercolour pieces on paper or mixed-media supports.
Advantages
The tube presentation allows precise control of paint quantity and reduces waste compared with pans. Transparent formulation facilitates clean glazing, smooth washes and subtle layering. The paint is water-soluble when wet and becomes water-resistant once dry, enabling predictable behavior during working and preservation of layered effects. The 21 ml size balances portability with sufficient volume for multiple sketches or small paintings.
Suitable for
Field sketching and plein air watercolour studies
Layered glazing and transparent washes
Illustration, mixed-media papers and sketchbooks
Color mixing and tonal studies
Key specifications
Formulation: transparent watercolour
Volume: 21 ml
Colour family: blue — Prussian Blue shade
Vehicle: water-based binder
Properties: good tinting strength, consistent flow, suitable for glazing and washes
Compatibility: designed for paper and mixed-media supports
How to use
Squeeze a small amount of paint from the tube onto a palette or mixing surface and dilute with water to reach the desired transparency or wash. Use soft or synthetic brushes for smooth application and build color with successive transparent layers, allowing each layer to dry if distinct glazing is required. For mixes, combine small amounts with other watercolour pigments on the palette to test hue and strength before applying to the paper.
Usage recommendations
To maintain color clarity when glazing, clean brushes thoroughly between layers and use clean water. Store the tube capped and in a cool, dry place to preserve pigment quality and prevent drying in the nozzle. For archival results, use appropriate watercolour paper and allow artworks to dry fully before framing or mounting.
