Dear Marius,
>From the documentation (see ?trellis.device):
"Note that this only applies to the initial choice of colors, which
can be overridden using 'theme' or subsequent calls to
'trellis.par.set' (and by _arguments supplied directly in high level
calls for some settings_)." [emphasis added]
xyplot() is a high level function; so my guess is that it overrides
the colour set in trellis.device().
HTH,
Josh
