Rublev Colours Dry Pigments - Series 6 Cadmium Yellow Deep is a premium, modern inorganic yellow pigment prized for its strong opacity, powerful tinting strength, and exceptional permanence. Cadmium Yellow Deep (PY 35) is made from cadmium zinc sulfide (CdS, ZnS), produced by co-precipitating cadmium and zinc salts and then calcining at high temperature to create a partially crystalline pigment structure. The result is a rich, saturated deep yellow that holds its brilliance under demanding conditions.

Cadmium pigments are widely regarded as the most durable yellows, oranges, and reds available to artists and industry. They offer excellent chemical stability and heat resistance, making them suitable for high-performance applications where colour must remain strong over time. For artists making their own paint, Cadmium Yellow Deep is a reliable choice for traditional binders and studio practice, including oil paint, egg tempera, encaustic, and other hand-mulled paint methods where you want clean, lasting colour and confident coverage.

With a mean particle size of 0.7 microns, this pigment can be dispersed for smooth, even colour. It has a moderate oil absorption (about 21 g oil per 100 g pigment), making it practical for grinding into an oil paste.
