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