Hayden,

It's not possible if you draw using the same color.  You'll have to use 
a different color index...

For example:
include graphics.e

sequence old_green
integer error

error = graphics_mode(18)
draw_line(BLUE,{{100,100},{200,100}}) -- draw blue line
old_green = palette(GREEN,{15,14,10}) -- redefine green (color index 2)
print(1,old_green)
-- draw second line using our redefined green 
draw_line(GREEN,{{100,200},{200,200}})
