Thanks for confirming that I am on the right track!

Goal:
Lattice should have good default settings for color, grayscale and
b&w.
The user should not be bothered with the details (similar to using
LaTeX: Many users do not have any idea of DEK's typesetting in the
background).
Lattice functions should provide reasonable default settings.
The default colors for the lattice suite were chosen for a reason
(very good choice for color display).
IMO the default grayscale colors should be wrapped into a similar
default-suite after discussion of which grayscales are best suited for
printing with different common resolutions using b/w printers.
After this has been decided upon, it might be nice to have something
along the lines of:
lattice.options(default.theme = [color|gray|bw])
Have I described my concern elaborately enough?

This looks very interesting, thanks for keeping the development going!
Cheers,
