What about black: solid in lift; dotted in sink?

Piece of PocketPC based moving map display software. Trace of flight shows
areas of lift and sink. My first instinct was to make trace green when in
the lift and red when in the sink. Not too clever when a whole bunch of
you
are red/green colourblind!

So, any suggestions on this one? How about blue and yellow? Yellow washes
out very easily on a sunlit PDA screen.
