A J Ludlow Cadmium Red Professional Watercolour

Cadmium Red is just one of the bright and exquisite Professional Watercolours made in the UK by A J Ludlow. Being based on a single pigment with excellent permanence and light fastness, ensures that this watercolour’s properties are exceptional.

Cadmium Red Professional Watercolour is prepared using a mixed crystal inorganic pigment, cadmium sulphoselenide (sulphide selenide). The pigment is a solid solution of cadmium selenide in cadmium sulphide; the ratio of which will influence the pigment’s hue as the more cadmium selenide the redder the pigment will be.

The pigment has excellent heat stability, a high degree of light fastness and chemical resistance, making it ideal for use in A J Ludlow’s Professional watercolour range. It's a bright and intense red that can be used on the artist’s palette as a brilliant mid-shade red or warm primary red, which can be mixed with yellows to create warm oranges and with blues to give a selection of purples. As with all cadmium pigments this colour is opaque in heavier layers, but in thin washes, Cadmium red is bright and shows good transparency due to the fact that only the pure pigment is used and the degree of pigmentation ensures a strong colour even when heavily diluted.

Although containing cadmium, this metal’s bioavailabilty in the pigment used in our watercolour is very low and so the pigment is considered safe for use in our Professional watercolour range.
