color: inline the 'showlabel' method

color: inline the 'showlabel' method

This function is quite simple and only have one call site… located a handful of line
under the definition. We inline the function for the sake of simplicity. One of
the motivation to do that now is that it reduce the amount of new method we
will have to add to the core 'ui' class for color support.
