static Color de.fu_berlin.inf.dpp.ui.util.ColorUtils.addLightness	(	Color	color,
		float	lightness
	)		[static]

Increases a color's lightness

Parameters:

color
lightness	by which the color's lightness should be increased; range: -1 (results in black) to +1 (+1 results in white)

Returns:

the new color

Note: Please keep in mind that a new color is created. Both the already existing and the scaled need to be disposed after usage!
