st: changing the default colors in a twoway graph

[Wendy Regoeczi <w.regoeczi@csuohio.edu>]

Hello everyone,
Does anyone know whether it is possible to change the default colors in a 
twoway graph? I am graphing two quadratic equations in the same graph; one 
line appears in blue and the other in red (I assume these are the 
defaults). But when I print the graph on a non-color printer, the lines are 
indistinguishable from each other - they both look black. I thought the 
situation might improve if I could ask STATA to graph one line in black and 
the other in light gray, but I can't figure out the correct command (if one 
exists) to accomplish this. I would be greatly appreciate any advice anyone 
might have.

Sincerely,
Wendy Regoeczi
