6. Selecting and Modifying Fixture Parameters 165
The Colour Picker will change its display according to the fixture selection:
With no fixtures selected, you just see the Colour wheel with saturated Colours around
the outside, and paler Colours towards the centre.
When a calibrated fixture is selected, a dashed line will be superimposed on the Colour
wheel. This line represents the fixture's gamut, or range of Colours that it can achieve.
To select any Colour within this range, simply click on it. The new selection will be
marked by a superimposed cross and circle. If you select a Colour outside the fixture's
gamut, one marker (‘X’) indicates the Colour that was chosen, while a second (‘O ’)
indicates the closest Colour that the fixture can produce. The two markers are joined by
a line to indicate they are related.
Fixtures that do not have Colour mixing capabilities do not appear in the Colour Picker.
If you have several different fixture types selected, the lines on the Colour picker
change to display the range of Colours that all of the selected fixtures can achieve
(shown as a dotted line), as well as the range of Colours that at least one of the fixtures
can achieve (shown as a dashed line). When you select a Colour, a single target marker
(‘X’) is displayed, connected to a series of ‘O’ markers, one for each fixture type.
The Colour Picker also displays the gamuts and markers for fixtures that are currently
in the editor, but not selected. These are shown in grey.
Fixtures that are not colour calibrated use a standard HS method and the Colour Picker
will appear without any dashed lines.
