In the RGB color model, which uses red, green and blue light in various combinations to make all the colors on computer and television screens, it is made by mixing red and green light.
In Northern Europe, Jan van Eyck featured rich earth browns in his portraits to set off the brighter colors.
The 17th and 18th century saw the greatest use of brown.
Brown exists as a color perception only in the presence of a brighter color contrast.
Yellow, orange, red, or rose objects are still perceived as such if the general illumination level is low, despite reflecting the same amount of red or orange light as a brown object would in normal lighting conditions.
Rembrandt also began to use new brown pigment, called Cassel earth or Cologne earth.
