Normal label text will work if we do `g.setColor(fgColor)` but html label will use [StyleSheet.paint](https://github.com/openjdk/jdk/blob/master/src/java.desktop/share/classes/javax/swing/text/html/StyleSheet.java#L1939) which does not take into account foreground Color (guess unless it's provided by html tags which is not the case here) so I need to explicitly set the foreground color of label

In addition to that, it is to be installed if and only if `label.setForeground` is `null` or `instanceof UIResource`, and uninstalled if it is `instanceof UIResource`. If the user explicitly set foreground color of the label, it must not be overridden by the L&Fs.

Fair point..Updated to set in installDefaults
