Burnt umber is a rich, dark brown pigment made from natural clay that has been heated to enhance its color. It is commonly used in painting and art, providing depth and warmth to various artworks. The pigment is known for its excellent lightfastness, meaning it resists fading over time when exposed to light. This color has been utilized since ancient times, appearing in cave paintings and later in Renaissance art. Artists appreciate burnt umber for its versatility, as it can be mixed with other colors to create a range of tones, from warm earth shades to cooler, muted hues.
