Apple Green is a light green colour that tends toward white, and also marks the transition to the latter. It is a mixture of grass green and a little white. Because this colour is peculiar to some kinds of apples, the name has been borrowed from them. In the fossil kingdom they are found in the fine chrysoprase (from Cosemüß in Silesia) and in cupronickel ochre.
