The green function extracts the green component of a color and returns it. Colors contain four components: red, green, blue, and alpha. To construct a color from the individual components, use the rgb or rgba functions.
Examples:
green(rgb(1, 0.2, 0)) ; 0.2 green(rgb(0.5, 1, 0.3)) ; 1.0 green(hsl(2, 1, 0.5)) ; 1.0
