DESCRIPTION
d.background will fill the image (or generally display monitor) with a single color specified by the color option.

NOTES
d.background is a frontend to d.erase and shares its limitations. Namely, it does not work with the wx monitors such as d.mon wx0.

EXAMPLES
In this example, the streets_wake map from the North Carolina sample dataset is displayed with custom background color (specified using HTML hex color code) using cairo display monitor (creates file called map.png):

g.region vector=streets_wake
d.mon cairo
d.background color=#ADEFD1
d.vect map=streets_wake color=#00203F legend_label="Streets"
d.legend.vect -b at=70,30 title="Wake County"
