Raw umber is a natural pigment characterized by its earthy brown color and is commonly used in painting, drawing, and other artistic applications. It is predominantly composed of iron oxide, manganese oxide, clay, and silica, which imparts its unique properties. The term "raw" emphasizes that it is not processed or refined, thus retaining its natural composition and color.
As a pure pigment, raw umber possesses a dark brown hue that can vary in intensity, ranging from a lighter, more yellow-brown shade to a deeper, reddish-brown tone. It is frequently sought after for its ability to create rich, earthy tones, and is often used in landscape paintings, as well as for creating shadows and depicting nature scenes.
Raw umber has excellent lightfastness, meaning it is resistant to fading or discoloration when exposed to light. This makes it a reliable and durable option for artistic works that require long-term preservation. Additionally, raw umber has a relatively low tinting strength, meaning that it only slightly influences the color properties when mixed with other pigments.
Furthermore, raw umber is often available in various forms, including dry pigment, tubes of oil paint, or as a watercolor or acrylic paint. Artists can choose the form that best suits their preferred medium and technique. Its versatility, natural richness, and steadfastness have made raw umber a staple in the artistic world, appreciated for its ability to provide depth, warmth, and a touch of natural beauty to art pieces.
The word "raw umber" comes from the combination of two different sources.
The term "umber" finds its origin in the Latin word "umbra", meaning "shadow". In ancient Rome, "umbra" referred to a dark earth pigment used to create shading effects in artwork. Over time, "umber" in English developed to denote a specific type of brown pigment derived from natural iron oxide deposits.
The word "raw", on the other hand, is an Old English term "hreaw", which originally meant "uncooked" or "not processed". In the context of "raw umber", the term signifies the natural state of the pigment before being processed or mixed with other pigments to create different shades.
Therefore, "raw umber" refers to the natural, unprocessed form of the brown pigment derived from the earth—resembling a shadow-like color.
