Winsor & Newton Cotman Watercolor

 

 


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.


Pigments

Costs are kept to an economical level by replacing some of the more costly pigments with less expensive alternatives. Pigments derive from a number of sources: Some are natural products, notably the earths, ex. umbers, ochres; others come from metal compounds and are sometimes termed 'traditional' or 'genuine', eg. ultramarine.


The distillation of petroleum yields an ever widening range of organic pigments which are often termed as 'modern'. Many of the pigments used in Cotman are organic.


Transparency

As water colour films are so thin all colours appear more or less transparent when painted onto paper. The pigments used in Cotman are also predominantly transparent.
