Field Detail

INSTANCE

public static final RandomColor INSTANCE

A ready-to-use random color generator.

Constructor Detail

RandomColor

public RandomColor()

Constructs a random color generator using the current time as a seed.

RandomColor

public RandomColor(long seed)

Constructs a random color generator using specified seed.

Method Detail

nextColor

public Color nextColor(float saturation,
                       float brightness)

Returns a random color.

Parameters:

saturation - the saturation of the color (range 0.0-1.0)

brightness - the brightness of the color (range 0.0-1.0)

Returns:

a random color having specified saturation and brightness

getRandomBackground

public static Color getRandomBackground()

Returns a random color which is suitable as the background of a Component. Equivalent to INSTANCE.nextColor(0.075F, 0.99F) when the LAF has a light theme.

This method is thread-safe.
