That was tongue-in-cheek on my part.  I just love the government telling 
me which direction I should walk in.

I sometimes use the altimeter in my Garmin 76CSx, but it's a 
automatically GPS-calibrated barometric altimeter, and quite accurate.

Otherwise, I just look it up from several sources and get a rough consensus.

Orange triangle is the present standard according to: 
http://www.parks.tas.gov.au/file.aspx?id=6789

Red is the nearest colour available from 
http://topo.geofabrik.de/symbols_en.html

As they say, the symbol (if used) should approximate the one walkers 
will see on the track, or be otherwise meaningful rather than just 
looking nice.
