Liquitex
Uncapped

Concerns about the safety of this pigment have been bubbling for years. Until recently, cadmium hue colors were the only option for artists wanting to avoid the heavy metal pigment. These give results in the same ballpark, but a pale imitation of the real thing, lacking in strength, vibrancy and overall performance. While the level of soluble cadmium used in paints doesn’t pose a significant risk to artists, there are concerns about its environmental impact. There’s been discussion about banning cadmium from the art world but no universal view.

In 2014, we started to look for a better solution. We set out to make the world’s first cadmium-free acrylic paint with the same performance, vibrancy and lightfastness as cadmium paint. But how do you make an acrylic behave like a cadmium color without any actual cadmium? Fans of cadmium said it couldn’t be done. But our chemists like a challenge.

New pigment advances unlocked the answer. The Liquitex lab team used a range of developments in organic and inorganic pigment technology. It was a meticulous three-year process, making use of the very specific optical and mixing qualities of a spectrum of pigments. Their process: Combine. Test. Adjust. Repeat.

What does it take to make a cadmium-free acrylic with the same characteristics of a cadmium, but without the risks? The team developed an identical cadmium-free match, but before they were satisfied with the results, they put the new formula through a final round of lab tests. These included archival lightfastness measurements. Color mass tone checks for brightness and overall match. Viscosity and rheology tests to see how it handled. Color reduction evaluation - 10:1 with titanium white to compare color strength and shade when mixed. Specific gravity checks to test weight and opacity tests.

We cut out the cadmium and our tests demonstrated that we could keep the identical much-loved character. So, we decide to challenge our artists to spot the difference! We prioritize involving the art community in all of our efforts, so we gave out thousands of free blind test sets. After a month of using the two tubes (one cadmium color, one cadmium-free), the results spoke for themselves. The colors were so hard to tell apart that artists actually argued over which was which.

Available in Heavy Body, Soft Body and Acrylic Gouache, the Liquitex cadmium-free range is made up of three reds, one orange and three yellows. Each gives matched visual and physical performance without the health or environmental concerns of cadmium.

The response from artists and our art retail partners has been incredible. With or without? It seems everyone loves to have a choice. You can find the Cadmium-Free alternative easily by looking out for the bottle and tube labels with green type.
