Parameter

Parameter	Description
original	Original color.
brightnessSource	Brightness source.

Return

Derived color that has the same hue and saturation as the original color, but its brightness is shifted towards the brightness of the brightness source.

Declaration

public static Color deriveByBrightness(Color original,
        Color brightnessSource)

public class Main {
    /**/*from w  ww  .ja  v  a  2 s. c om*/
     * Derives a color based on the original color and a brightness source. The
     * resulting color has the same hue and saturation as the original color,
     * but its brightness is shifted towards the brightness of the brightness
     * source. Thus, a light red color shifted towards dark green will become
     * dark red.

     * @param brightnessSource
     *            Brightness source.
     * @return Derived color that has the same hue and saturation as the
     *         original color, but its brightness is shifted towards the
     *         brightness of the brightness source.
