Overview
A 20-tube starter set of Winsor & Newton's Cotman watercolors, each tube 5 ml (0.17 oz), spanning a standard range from Chinese white through lamp black.
Cotman is Winsor & Newton's student line, built by swapping some costlier pigments for less expensive alternatives while keeping the same paint-making process as their professional Artists' range. That tradeoff is worth knowing going in: good transparency and tinting strength, at a price built for someone still deciding whether they'll stick with watercolor.
- 20 tubes, 5 ml (0.17 oz) each
- Winsor & Newton's student-grade Cotman line
- Good transparency and tinting strength
- Includes Ultramarine, Burnt Sienna, Lamp Black and more
Who it's for
Good for someone starting watercolor who wants a recognized paint brand without paying for professional-grade pigment. Less suited to an experienced painter chasing maximum lightfastness or pigment purity.
Pros and cons
- 20-color range covers most subjects out of the box
- Good transparency and tinting strength
- Recognized brand at a student price
- Tubes stay workable rather than drying rock-hard
- Uses some hue substitutes instead of the named pigment
- Lightfastness rated below Winsor & Newton's professional line
Performance notes
Cotman colors are formulated for good transparency and tinting strength with a uniform consistency, which Winsor & Newton positions as easier for new painters to control than some professional paints. Lightfastness is rated good rather than the top rating reserved for their Artists' range.
