Winsor and Newton Cotman Watercolours - 8 ml Tubes - at least 30% off - Winsor and Newton Cotman Water Colours are a range of water colours that are made to our normal high quality standards but costs are kept to an economical level by replacing some of the more costly pigments with less expensive alternatives. The range consists of 40 colours in tubes and pans which possess good transparency, excellent tinting strength and good working properties. There are also a number of excellent water colour sets available in the Cotman range. The Cotman Water Colour range has a more uniform consistency than the Artists Water Colour range and this benefits beginners as there is less to learn about each individual pigment. The Cotman Water Colour range also relates to the Winsor & Newton Artists Water Colour range, e.g. Burnt Sienna in both ranges has the same hue. This enables artists to use colours from both ranges with minimal adjustment to their technique.
