The unfortunate thing about the above solution is that it does
not cause the ocean to be a color which is different
from the continents. I am running IDL 4.0b3 (a beta version).
Here is a plug for purchasing IDL 4.0 since I believe my solution
(in whole) cannot be done with an earlier version of IDL.
Here is an example...

BLUE=33 ; For my personal color table 33 is blue.
map_set, /cyl
polyfill,!x.window([0,1,1,0,0]),!y.window([0,0,1,1,0]),color =BLUE,/norm

map_continents, /fill, color=!p.background ; Fill in the continents
map_continents ; Draw continental outlines

This works for an Xterm and any other color output device,
including postscript. They key is the NEW /fill keyword in map_continents.
If one does not mind having the ocean and continents the same color, then
one could omit the line with the /fill keyword.
