Since 1835 when William Winsor and Henry Newton introduced the first moist watercolours to the world, much of our reputation for supreme quality has stemmed from the Professional Watercolour range. Since then Professional Watercolour continues to be formulated and manufactured according to our founding principles; to create an unparalleled watercolour range which offers artists the widest and most balanced choice of pigments with the greatest possible permanence. Each colour within this wide and balanced spectrum has been selected and formulated to offer the greatest choice so that artists can use a unique palette that best suits their work.
