Umber is a natural earth pigment that ranges in color from yellowish-brown to dark brown. It is made from clay and iron oxide, which gives it its distinctive hue. Artists often use umber in painting for its warm tones and excellent blending properties. It can be found in both oil and watercolor paints. There are two main types of umber: raw umber and burnt umber. Raw umber is the unheated form, while burnt umber is heated to enhance its color, making it darker and richer. Both types are popular in art and design for creating shadows and depth in artwork.
