Rublev Colours Chrome Yellow Primrose is a bright, light leaning chrome yellow pigment based on lead chromate with lead sulfate (PY34). This primrose shade sits at the paler, slightly greenish end of the chrome yellow range and is valued for its strong opacity, excellent hiding power, and clean, high impact colour. Historically, chrome yellows were widely adopted in the 19th century for their brightness and cost effectiveness, and the primrose varieties were commonly adjusted with lead sulfate to achieve their lighter tone.

Chrome Yellow Primrose disperses readily in both oil and water based systems and offers strong tinting strength for professional paint makers who require a true chrome yellow look for historical colour matching, coatings, and specialist applications. Encapsulated or silicate coated grades are designed to improve resistance to darkening compared with untreated lead chromates.
