I searched the Help->Browse Manual for "color" and came up with

SetBackground. Set passed 24 bit number as RGB color of background. 

which is cryptic to say the least it means

(d-SetBackground 0)

would set the background to black. 
(d-SetBackground #x00ff00) turns red and blue off etc.
There is a Denemo procedure to get a color from the user, too. (d-
SelectColor) which returns a list of r, g and b values in range 0.0-1.0
that would need converting to use with d-SetBackground.
