Note that you also need to set the environment variable
GRASS_TRUECOLOR to TRUE, e.g.

Bourne shell:
	GRASS_TRUECOLOR=TRUE
	export GRASS_TRUECOLOR

C shell:
	setenv GRASS_TRUECOLOR TRUE

prior to starting the driver.

The default behaviour is to produce 8-bit images, for compatibility
with older versions of the PNG driver.
