graphics: COLOUR

colour_name

A character string (of length 20 or less) via which you will refer to the colour in REPRESENTATION instructions.

If the colour has already been defined, then its colour composition will be modified. On workstations which permit this, the change will be visible in currently displayed graphics that use the colour.

If the colour has not yet been defined, then it will be added to the colour table (provided there is still room).

The current definition of a colour will be shown if only a colour name is specified. All currently defined colours are listed if no arguments are given.

For the FOREGROUND colour, the red fraction is 1, for the BACKGROUND colour it is 0.

For the FOREGROUND colour, the green fraction is 1, for the BACKGROUND colour it is 0.
