PV 37 – Dioxazine Violet is a synthetic organic pigment belonging to the dioxazine family, renowned for its deep, cool violet hue and high chromatic intensity. Closely related to PV 23 (Dioxazine Purple), PV 37 exhibits a slightly bluer undertone, offering a more neutral violet that retains the exceptional lightfastness, chemical resistance, and transparency characteristic of dioxazine pigments. These properties make it a preferred choice for artists and industrial applications requiring durable, vibrant violet coloration.

Chemically, PV 37 is based on a fused heterocyclic dioxazine structure, which provides outstanding stability to light, heat, and solvents. Its molecular composition allows for strong tinting strength and consistent performance across a wide range of media, including oil, acrylic, watercolor, printing inks, plastics, and high-performance coatings. The pigment’s stability also ensures excellent permanence in both indoor and outdoor applications.

In artistic practice, Dioxazine Violet offers high transparency and deep chroma, enabling rich layering, glazing, and subtle modulation of violet tones. It mixes cleanly with whites, reds, and blues to produce a wide range of purples, mauves, and shadow tones without becoming muddy. Its cool undertone distinguishes it from warmer organic violets, making it particularly effective in complex color harmonies and precise color matching.
