The resultant colour spectrum ensures the largest number of colours can be mixed. 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, this enables artists to use colours from both ranges with minimal adjustment to their technique.
