Prussian Blue is a deep blue colour. It was made by German chemist Diesbach around 1704 making it the first synthetic blue pigment. It quickly gained favour as an alternative to genuine Ultramarine.
With 96 colours, the Professional water colour range offers bright, vibrant colours and unrivalled performance.Water colour more than any other medium relies upon the variable characteristics of the pigments used. Our Professional Water Colours use only the purest pigments, and are known for their brilliance, permanence and strength of colour.
With 75 single pigment colours in the range, we offer the widest range of modern and traditional pigments for superb colour mixing.
The transparency of Professional Water Colour is due to the way the pigment is dispersed during manufacture. In thin washes, the colour is present but the reflective white of the paper can still be seen. The colours provide brilliance and clean mixing and the natural characteristics of pigments mean that some will be more transparent than others.
93 out of 96 colours in our Professional Water Colour range are classed as "permanent for artists' use”, rated AA or A for permanence to ensure that the colours used today will appear the same for generations to come.
