[R] change fitted line colour in lme() trellis plot?

If I used a groupedData object, if I do 
produces a nice trellis plot of the data along with the fitted lines

However I find that the lines and the data points are in the same colour
(light blue against a medium grey background). Is there a way to make
the lines in a different colour (e.g. black)? It would also be nice if
the line were plotted after the points so it is visible (I have a lot of
points and the line is obscured).

I have looked at par().

Thanks very much for any help.
