Winsor & Newton Cotman Watercolour Paint, the 8ml tubes range consists of 40 colours which possess good transparency, excellent tinting strength and good working properties. Cotman Water Colours are a range of water colours that are made to Winsor & Newton's normal high quality standards but costs are kept to an economical level by replacing some of the more costly pigments with less expensive alternatives.
I have been using this range of watercolour paints for 10 or 12 years now and have never had any cause for complaint.
Their quality is consistent and certainly good enough for a fairly serious amateur painter like myself. Over the years the fidelity of the colours has never varied - you always get what you expect.
I have no hesitation in giving these paints an excellent rating. John Smith (Dumfries, United Kingdom) on 24 Nov 2015
This range of watercolour paints is the best I have come across, with some excellent quality pigments for a student level, especially raw sienna and permanent rose. Excellent! Anthea COPLESTON (Liverpool, United Kingdom) on 24 Apr 2015
Winsor & Newton Cotman Watercolours are ideal for a new artist setting up a stock of colours or somebody on a lower budget. The colours are consistent, the paint is a good texture and mixes well. The 8ml tubes will, in most cases, provide sufficient paint to last a considerable time. Gillian Pearson (Lincoln, United Kingdom) on 19 Jun 2015
