Chromium-based greens expanded the pigment palette in the nineteenth century. Chromium oxide green and the hydrated pigment known as viridian belong to this wider history, but should not be treated as the same material.
Chromium oxide green is valued as an opaque mineral green with good stability in appropriate applications. It can contribute a quieter green than the very intense greens made using some modern organic pigments.
Do not confuse chromium oxide green with every pigment called chrome green. Historic names sometimes describe different mixtures. Safety must be assessed from the specific material and its documentation, not the colour name.
These articles explain pigment and mineral families, not the sourcing or complete formulation of any Cameron Colours paint. Historical names can cover different materials. Follow the product guidance and safety data for the paint you use; do not handle or heat raw pigment powders at home.
