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
Color mixing correspond to ideal subtractive color mixing because some light from the subtracted color is still being reflected by one component of the original paint. This results in a darker and desaturated color compared to the color that would be achieved with ideal filters. The three primary colors in subtractive mixing that produce the largest gamut are yellow, magenta and cyan, leading to the CMYK color model widely used in color printing. Historically, painters have used yellow, red and blue in place of these, resulting in reduced gamut. In subtractive mixing of color, the absence of color is white and the
