lightenColor
Lightens up a color for groove, ridge, inset and outset border effects.- Parameters:

- the sRGB equivalent
-
isSameColor
Checks if two colors are the same color. This check is much more restrictive thanColor.equals(Object)
in that it doesn't only check if both colors result in the same sRGB value. For example, if two colors not of the same exact class are compared, they are treated as not the same.Note: At the moment, this method only supports

andColorWithAlternatives
only. Other subclasses ofColor
are checked only using theColor.equals(Object)
method.- Parameters:
