## set display

`set display grey|greyscale|color <black|white>`

Sets the mode of the display.

By default, the mode is `color`, where shading and contouring is done with a rainbow of colors. When using a monochrome display, these colors may not map to greyscale in a pleasing way. When the mode is set to `greyscale`, contours are displayed using a single grey level, and shaded contours are done using a sequence of greyscales.

You may optionally set the hardware background color to `black` or `white`. The default is `black`.

Issuing: `set display grey white` gives a result on the display that is very similar to the output produced by `gxps`.
