Winsor & Newton Professional Watercolour Tube
First introduced in 1832 by Henry Newton and William Winsor as the first moist water colours, Winsor & Newton still place these Watercolours at the heart of the company. Wherever possible, single pigments have been used in Winsor & Newton's Professional Water Colour to ensure the widest choice of colours and pigment characteristics, such as hue, particle size, transparency and tinting strength.

More Detail
The use of single pigments is advantageous as the pigments are purer in hue and cleaner in colour than mixtures of pigments, ensuring a larger number of colour mixes before resulting in muddy effects. Winsor & Newton's Professional Watercolours offer an unparalleled range of 96 colours in 5ml tubes, presenting the artist with a wide and most balanced choice of pigments with the greatest possible permanence.
