### Parameters:

color=name [required]

## 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"
