static java.awt.Color	darken(java.awt.Color color, int byPercent)
static java.awt.Color	desaturate(java.awt.Color original, int percentage) a very simple implementation that assumes r,g,b to be equivalent to luma, so we don't have to convert RGB to HSV in order to reduce the saturation level.
static java.awt.Color	lighten(java.awt.Color color, int byPercent)
static java.awt.Color	lightenDarken(java.awt.Color color, int byPercent, boolean darken)

Method Detail

desaturate

public static java.awt.Color desaturate(java.awt.Color original,
                                        int percentage)

a very simple implementation that assumes r,g,b to be equivalent to luma, so we don't have to convert RGB to HSV in order to reduce the saturation level. For this reason, the result may not be 100% accurate, but for instances in which merely a "different color" is needed, e.g. for approved / non-approved objects, this is plenty sufficient.

Parameters:

original - the original color to desaturate

percentage - the percentage by which the color should be desaturated

Returns:

the desaturated color

lighten

public static java.awt.Color lighten(java.awt.Color color,
                                     int byPercent)

darken

public static java.awt.Color darken(java.awt.Color color,
                                    int byPercent)

lightenDarken

public static java.awt.Color lightenDarken(java.awt.Color color,
                                           int byPercent,
                                           boolean darken)
