Section: Background Colour
Windows can have a back-colour, specified as one from the (reasonably large) Table of Common Color Values (based on but extended from Glulx Text Effects, by Emily Short). The possible colours are:
g-darkgreen, g-green, g-lime, g-midnightblue, g-steelblue, g-terracotta, g-navy, g-mediumblue, g-blue, g-indigo, g-cornflowerblue, g-mediumslateblue, g-maroon, g-red, g-deeppink, g-brown, g-darkviolet, g-khaki, g-silver, g-crimson, g-orangered, g-gold, g-darkorange,g-lavender, g-yellow, g-pink.
and they are assigned by including a line like so:
The side-window has back-colour g-red.
The main-window has back-colour g-darkgreen.
At present, colours in graphics windows are reasonably well-supported (and if not, are unlikely to do any harm). Background colours in text windows can cause a series of ugly effects; such as the colour only appearing behind printed characters, or the background colour copying itself into all other text windows.
The main-window can be supplied a background colour in the same way.
