Inorganic –
Cerulean Blue 603 is a cool, slightly greenish blue with excellent lightfastness and opacity. Made using PB36 (Cobalt Chromite Blue Green), this pigment offers a stable, non-reactive alternative to more traditional cobalt-based blues, with a characteristic soft, sky-like tone.
Ideal for skies, seascapes, and subtle mixing, Cerulean Blue is a valuable addition to any artist’s palette. Its moderate tinting strength allows for nuanced control in blends, while its granulating properties add natural texture and depth.
