A range, which is suitable for both amateur artists and the accomplished artist who requires large volumes of colour at an economical price.The range of 40 colours is chosen according to mass tone (colour from tube), undertone (bias of colour when in a thin film), colour strength, relative opacity and the character of the pigment itself. The resultant colour spectrum ensures the largest number of colours can be mixed. Winsor & Newton Cotman provides a comparatively inexpensive selection of good quality watercolours. Colours include both useful traditional pigments, and reliable synthetic colours that replace some of the more rare and expensive pigments.
