In ancient Egypt, green, or wadj, represented new life, fertility and green vegetation. Red, or desher, also represented life, but it focused more on mature life, blood and action. Black was sometimes associated with new life, but it was just as closely associated with death and resurrection.
Colors were highly symbolic to the ancient Egyptians. Blue, red, green, black, white, yellow and the silver and gold of moon and sun were all used in art to express more than the hieroglyphs and images could. Colors were used as a form of symbolic magic; painting oneself red with ochre, for instance, was thought to bring victory in battle and eternal life. Artists took pains to keep colors pure and sharp, painting entire scenes with one color at a time.
