It referred to the colour of undyed buffalo leather, such as soldiers wore as some protection: an eyewitness to the death in the Battle of Edgehill (1642) of Sir Edmund Verney noted "he
Secondary color out to be good primary colors for pigments, the mixing of which subtracts light. Pigments, such as inks and paint, display color by absorbing some wavelengths of light and reflecting the remainder. When pigments are combined, they absorb the combination of their colors, and reflect less. Thus, combining pigments results in a darker color. This is called subtractive color-mixing, as mixing pigments subtracts wavelengths from the light that is reflected. The mixture of equal amounts of these colors produce the secondary colors red, blue, and "lime" green (the RGB primary colors of light), as follows: That is, the primary and
