Since 1832, when William Winsor and Henry Newton introduced the first moist watercolours, much of the reputation for supreme quality held by Winsor & newton has been based on the Artists' Watercolour range. This range of 91 Colours offers a wide, balanced spectrum with each colour being specially selected to offer the greatest choice ensuring all artists can choose a palette which suits their work. Each colour within the range has been individually formulated to take advantage of each pigment's characteristics and to ensure colour stability. Blends of high performance pigments ensure excellent strength and brilliance of colour while single pigment formulations have been used whenever possible to ensure cleaner, brighter mixes. Permanent alternatives have been developed for the less durable traditional colours, without compromising handling properties.
