Winsor & Newton Professional Watercolour Half Pan Viridian — Transparent, AA permanence

Winsor & Newton Professional Watercolour Half Pan in Viridian is a professional-grade, transparent green paint formulated for brilliant, long-lasting colour in watercolour painting.

This half pan contains Viridian from Winsor & Newton's Professional Watercolour line, a pigment selection created for artists who need clarity, mixing reliability, and archival permanence. The Professional range emphasizes single-pigment purity and a manufacturing dispersion process that preserves the pigment's natural transparency, making washes luminous and colour mixing predictable. This Viridian sits in Series 3 with Colour Code 692 (Colour Index PG 18) and carries an AA permanence rating, suited for artwork intended to endure.

How will this Viridian behave in thin washes and layered glazes?

Viridian from this professional series stays true when diluted, offering clear, even washes that reflect the paper's brightness. Because transparency is a feature of the formulation, layering builds depth without muddying adjacent hues.

• Transparent pigment that allows underlying paper to shine through
• Consistent dispersion prevents streaks in light washes
• Layers remain distinct for glazing techniques

What makes this Professional Watercolour different from student-grade paints?

The Professional line uses high-grade pigments and a manufacturing method that preserves their optical qualities, providing fuller chroma and superior permanence versus student formulas. Expect fewer fillers, stronger tinting strength, and archival ratings suitable for gallery work.

• High pigment load for richer colour and better tinting
• Rated AA permanence for long-term stability
• Minimal extenders or fillers to keep mixes clean

Which surfaces and techniques is this half pan best suited for?

This Viridian half pan performs well on watercolour paper, both hot-pressed and cold-pressed, and adapts to washes, wet-in-wet, drybrush, and lifting. Its transparency and tinting strength make it useful for botanical greens, landscapes, and subtle colour shifts when mixed with other pigments.

• Ideal on 100% cotton and high-quality watercolour papers
• Works for glazing, washes, and fine detail when rewet
• Mixes cleanly with warm and cool pigments for varied greens
