As part of his teaching, Cotman operated his own version of a watercolour subscription library, so that his pupils could take home his drawings to copy. [13] In 1810, Cotman began to etch, and the following year his first set of etchings ( Miscellaneous Etchings) was published, strongly influenced by the work of the Italian artist Piranesi. [13] All but one of the subjects were architectural, and were mostly of Yorkshire buildings. [18] He later published a set of etchings of the ancient buildings of Norfolk ( Architectural Antiquities of Norfolk (1818). [13] There are the warm and cool version for yellow, red and blue which are the three primary colours. Then there are 5 convenient mixtures of two greens and three earth colours. It's quite a complete set in terms of colour selection. Well, the Cotman colours are less intense then the Artists grade. I feel that they are slightly chalkier too. When the watercolour is dry, the result is still quite respectable as you can see in the colour chart further below, just that it takes more effort to use them. When you compare side by side with Artist grade watercolours, the difference is clearer. This is the Winsor & Newton Metal Sketchers' Box. The lid has four partition, in addition to another hinged flap, that can be used as a palette. There is a thumb ring beneath the box. Traditionally the white of the paper provides the brilliance to water colour and can be used as highlights. However, some artists utilise Chinese White for highlights at the end of their painting or in dulling some colour mixtures down.

A comprehensive catalogue by Emeritus Professor David Hill of The University of Leeds, covering the entire Leeds collection of Cotman sketches and watercolours, together with one oil painting. Watercolour paint is made of pigment and binder. The amount of pigment controls the intensity of the colours. Binder holds the pigment (typically power) together. The more binder there are, the less intense or saturated the colour is. You can make a colour less intense by mixing or adding water, but you can't make a colour more intense than it is initially. So what you want is to start out with an intense colour. Binyon, Laurence (1897). "John Sell Cotman". John Crome and John Sell Cotman. London: Seeley & Co. LCCN 10012634. Hill, David (2005).

Winsor & 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.It has a good selection of commonly used colours. Other larger box sets adds more colours to this list.

However, if you’re looking for less time and less paint, a pan might be a better option. Because of the half-pan design, only a third of the amount of paint is required to achieve the same color as with a tube. Pans are also more affordable, with an added advantage of being longer-lasting. There is no absolute correct answer; it depends on the task at hand. If you want to paint delicate watercolors, you should go with a tube. If you want to make a more vibrant painting, a pan may be a better option.

They are all pan sets. Additionally, Winsor & Newton also offers tube sets! And these are just for the Cotman series. Their Artist watercolours uses the same boxes but they also offer the heavyweight enamelled box sets.
