Palettes
Palettes provide a selection of pre-defined settings for Lamp Colours and
Beams. Each time a new Lamp Type is selected, the Lamp Definition is
used to set-up some default options in each Palette; these options can
then be added to or modified as required.
Two Palettes (Colour and Beam) are created for, and are common to, each
Lamp Type that you are using. For example, if you are using 20 Lamps of
the same type, all 20 Lamps will share the same two Palettes. This is an
important point to remember, since any modifications or additions made to
a Palette will apply to all Lamps of the same type.
If you apply a Palette option to a group of Lamps of different types (i.e.
they are using different Palettes), all Lamps will be set to the same ‘option
number’, but will derive the actual Attribute settings from their associated
Palette. As far as possible, the default Palette options are matched
between Lamp Types. For example, if option 5 on one Colour Palette
selects ‘orange’, option 5 on another Palette will also be orange, or a
similar colour (e.g. red).
Lamp Attributes
Ventura allows the following Attributes to be set for each Lamp, however
not all of these will be applicable to all Lamps:
 Colour,
 Beam,
 Position,
 Intensity.
The Colour and Beam Attribute for each Lamp can be set by one of two
possible sources:
 An absolute value , which is unique to that Lamp, or
 A palette number , which is common to all Lamps of the same
Type.
Lamp Positioning
The Position for each Lamp can use one of two possible values:
 An absolute value, which is unique to that Lamp, or
 A pre-defined position number, which is also unique to that Lamp;
these may, of course, be programmed to match the preset
positions of other Lamps (of any Type).
Lamp Intensity
The Intensity value is always an absolute value and as such can be unique
to each Lamp.
