#### Description:

This attribute determines the colour index used when drawing each element of graphical output produced by a Plot. It takes a separate value for each graphical element so that, for instance, the setting `"` Colour(title)=2`"` causes the Plot title to be drawn using colour index 2. The synonym `"` Color`"` may also be used.

The range of integer colour indices available and their appearance is determined by the underlying graphics system. The default behaviour is for all graphical elements to be drawn using the default colour index supplied by this graphics system (normally, this is likely to result in white plotting on a black background, or vice versa).

Type:

  Integer.

#### Applicability

##### Plot

All Plots have this attribute.

#### Notes:

- For a list of the graphical elements available, see the description of the Plot class.

- If no graphical element is specified, (e.g. `"` Colour`"` instead of `"` Colour(title)`"` ), then a `"` set`"` or `"` clear`"` operation will affect the attribute value of all graphical elements, while a `"` get`"` or `"` test`"` operation will use just the Colour(TextLab) value.
