Purple ochre, also known as mineral purple, is a naturally occurring iron oxide pigment that is characterized by its distinct purple coloration. It is commonly found in the form of a clay-like mineral, with shades ranging from light lavender to deep violet. The name "ochre" is derived from the Greek word "okhra," meaning pale yellow, which reflects its origin as a yellowish-hued mineral.

It has particularly been favored as a pigment for creating vibrant purple shades in paintings, dyes, and ceramics. Its rich hue and durability make it highly sought after in the art world.
The composition of purple ochre primarily consists of iron oxide, with trace amounts of clay minerals. The presence of iron in the form of hematite or goethite is responsible for the pigment's purple coloration. The specific shade of purple ochre can vary based on the proportion of iron content, impurities, and geological factors.
Purple ochre can be found in several regions around the world, including Australia, France, and the United States. Its availability and varying qualities make it a popular choice for artists and craftsmen alike, who appreciate its versatility and distinct color properties.
Overall, purple ochre, or mineral purple, can be defined as a natural iron oxide pigment with clay-like consistency, ranging in color from light lavender to deep violet. Its rich hue and widespread availability have made it a valued coloring agent for artistic and decorative purposes throughout history.
