As per https://github.com/openjdk/jdk/blob/master/src/java.desktop/share/classes/javax/swing/border/BevelBorder.java#L151
and https://github.com/openjdk/jdk/blob/master/src/java.desktop/share/classes/javax/swing/border/BevelBorder.java#L183
`derived ` is used to obtain the darker or brighter version of the same color, which is being done here for this highlight and shadow color too.
