Parameter

Parameter	Description
orig	The original color.
darker	The amount by which to decrease its r, g, and b values. Note that you can use negative values for making a color component "brighter." If this makes any of the three values less than zero, zero is used for that component value; similarly, if it makes any value greater than 255, 255 is used for that component's value.

Declaration

public static final Color deriveColor(Color orig, int darker)
