Rublev Colours Dry Pigments - S6 Cadmium Red Light is a powerful, high-performance red pigment for artists and makers who want maximum permanence, opacity, and colour impact. Made from cadmium zinc sulfoselenide (CdS, CdSe), this modern inorganic pigment is produced by co-precipitation and high-temperature calcining to form a partially crystalline structure. The result is a brilliantly saturated cadmium red with exceptional durability and stability.

Cadmium pigments are widely regarded as the benchmark for long-lasting yellows, oranges, and reds. Cadmium Red Light (PR 108) offers outstanding resistance to light, heat, and many harsh environments, making it a go-to choice for mixing into traditional binders and professional applications where colour fade is not an option. It is well suited to making your own paints and mediums, including oil paint, egg tempera, encaustic, and other studio formulations where you want strong covering power and confident tinting strength.

With a mean particle size of 0.9 microns, this pigment can be dispersed for smooth, even colour. It has a moderate oil absorption (about 20 g oil per 100 g pigment) which makes it practical for grinding into a paste for oil painting.
