Subtractive Color Mixing
	• In 1869, Louis Ducos du Hauron (1837-1920) and Charles Cros (1842-1888), two Frenchman working independently announced their research on subtractive color mixing. • In subtractive mixing, which is the basis for modern color photography, colors are created by combining cyan, magenta and yellow dyes (the complements of red, green and blue). The dyes are subtract colors from “white” light that contains all colors.
