Red ochre pigment is classified into various types that differ in particle size and consistency. Below is a list of these types.
Natural Red Ochre
Natural red ochre is in some earth deposits and is unrefined. It is primarily composed of clay and iron oxide. Because it is natural, it contains other minerals and therefore can be gritty. Normally, it is used in artistic applications and construction, among other uses.
Ground Red Ochre
This type of pigment is made by grinding natural red ochre into fine particles. Its fine texture gives it a smoother application, thus making it suitable for pottery glazes and paints, among others. Fine red ochre is a commonly used raw material in many industries.
Bohemia Red Ochre
This is a specific type of red ochre pigment that originates from the Bohemia region in the Czech Republic. It is deeply characteristic due to the high iron content which provides a vivid red hue. Normally, it is used in artworks, especially in oil and acrylic paints.
Synthetic Red Ochre
This is produced artificially by combining iron oxide and clay in controlled settings. It offers consistent color and better purity. Synthetic red ochre pigment is popular in manufacturing and industrial applications.
Red Iron Oxide Pigment
This is a milled form of red ochre used in industrial applications. It is less likely to fade when exposed to harsh conditions, including external weather elements. Moreover, it has good coverage and is chemically stable. Often, it is used in construction paints, coatings, and polymers.
Red ochre pigment has multiple distinguishable features. Below is a list of these features.
Vibrant Color
Red ochre is outstanding for its vivid earthy red color. This is due to its iron oxide content which accounts for a large portion of its color. Because of its aesthetic appeal, artists incorporate it into their paints to get warmth and depth.
Heat Resistance
Red ochre pigment can withstand elevated temperatures without degrading or losing color. This property makes it suitable for use in outdoor applications and areas that are frequently exposed to high temperatures.
Non-toxic
As a natural element, red ochre pigment is non-toxic and safe for the environment. It can, therefore, be used in a range of applications from art to construction where safety is a key consideration. Unlike synthetic pigments that can release harmful toxins, red ochre is environmentally friendly.
Texture
Red ochre pigments have a coarse to fine granular texture depending on the grade required. This characteristic allows for versatile applications ranging from thick to thin paint textures. This property is one of its kind compared to other pigments that are uniform in granularity.
Lightfastness
Red ochre has exceptional lightfastness which means it will not fade when exposed to sunlight and other harsh elements for a long time. This property is crucial in outdoor paints and coatings. Also, it ensures durability and longevity in artistic endeavors.
Earthy Aroma
Red ochre pigment emits a natural, earthy scent since it is derived from the earth. It can, therefore, be used in cosmetics to provide a more organic feel. It is, furthermore, less artificial than other pigments and more pleasant.

Art and Painting
Red ochre pigment is widely used in art and painting because of its natural earth properties. Artists use oil and acrylic paints to achieve warm, earthy tones in their natural landscapes or human portraits. Red ochre pigment has good light fastness and therefore does not fade over time. This makes it preferred for both fine art and outdoor murals.
Cosmetics
Red ochre is a common ingredient in cosmetic products like mineral foundations and blush. It gives a natural reddish-brown color that complements different skin tones. In addition, it is sought after due to its organic nature and therefore does not contain harsh chemicals that may irritate the skin.
Construction Materials
Artists frequently use red ochre as a coloring agent in different types of building materials such as cement, bricks, and tiles. In most cases, it adds reddish hues to interiors and exteriors.
