You can do this from the shell (or your .profile) with the following:

	echo "\033[XXm" 

Where

	XX is the color/attribute specification.  See display(7) for a 
	complete list of what colors and/or attributes can be used.

While this does work at setting the color attributes, it does not
provide a satisfactory implementation because it doesn't cause the entire
screen to be colored.  Only characters output after that sequence are in
the specified color.  Another problem is that many programs (like vi) clear
the color/attributes by sending an \033[0m at startup time.

Most of the time people set thier colors in the shell command prompt so that
the colors are set/restored each time the prompt is displayed.
