An Introduction to Winsor & Newton Cadmium Free Watercolour and Gouache

by Cass Art

The first place to start is what is Cadmium?

Cadmium is a soft, silver-white metal found in the earth’s crust and throughout our environment. A lot of rocks and soil including coal and mineral fertilizers, contain some cadmium. It was only when it was discovered as a by-product of the zinc refining process that it became used as a pigment.

Cadmium yellow was the first pigment produced in around 1820 and was soon joined by an extended range of different shades of yellows and oranges created in the laboratory. The new cadmium colours, particularly the darker varieties, were more lightfast than existing choices and became a welcome addition to the artist’s palette. Cadmium pigments are much loved artists mainly due to their ability to deliver vibrant, lightfast results but there still are some concerns over the safety of this metal. Cadmium pigments are restricted for certain applications, but this restriction does not apply to paint. 

Cadmium v Cadmium Free

If you’re thinking of trying Cadmium Free watercolour but you're slightly concerned it won't be the same as the Cadmium colour you’re so accustomed to. Below are a series of extensive comparisons videos which will give you an insight into what exactly Cadmium Free is, how it performs compared to Cadmium in terms of performance, permanence, tinting strength and opacity. Enjoy!

So what are the key points with Cadmium Free?

• Bright and vibrant colours: finely milled, evenly dispersed
• Maximum transparency, even with opaque pigments - washes offer unparalleled colour graduation
• Lightfastness ensures art will last for generations

*Not to be confused with hue colours of course. These are a blend of other pigments to made up an imitation of an original pure pigment. These Cadmium free colours genuinely matched cadmiums and behave in the same manner.
