+<p> The graphical part of the Oric screen has 240×200 pixels and can only
+display 8 different colours (black, blue, red, green, cyan, magenta, yellow and

+either the foreground and the background colours, or the negative values
+thereof. The background <i>or</i> the foreground colour may also be changed
+(one at a time), but while doing so the next 6 pixels cannot be chosen: they
+will use the background colour instead. </p>
