The Classic Greek sculptures modeled the human body as if they were perfect. The men were sculpted muscularly, and the women were sculpted beautiful and slender. Later on, however, the sculptures became more realistic, depicting the flaws of the human body.
For example, purple was approximated by glazing blue over a reddish underpainting or vice a versa. Two, glazing creates, as we have said, an extraordinarily luminosity impossible to achieve otherwise. Only inherently transparent pigments, called lakes, are suited for glazing.
