A palette is a form of referenced data. This means you can record a set of values once and then refer back to this at any point in the future, without having to input those values from scratch again.
For example, if you found a specific shade of lavender you liked, you could record this into color palette 1. Now, if you ever want to access that shade of lavender again in the future, all you need to type is Color Palette 1.
You can use the live data currently on stage to record a palette. For example,
set your fixtures to the colour you would like and then type Record Color
Palette 1. Note that this will record the colours of everything which is not
currently in it’s default colour. In order to just record the colour of a few
channels, specify them before you record the palette. For example Chan 1 Thru
12 Record Color Palette 1 will ignore any channels other than 1 through 12.
There are five types of palettes in Eos: Intensity, Focus, Color, Beam and
Presets. The first four can record data about their associated parameter group
(Beam covers Form, Image and Shutter). Presets can record any combination of
parameter types. In order to specify which parameters you want to record, put
them in the command line when you record the palette. For example Chan 501
Thru 503 Intens Shutter Record Preset 1 will record only the intensity and
shutter values of 501 through 503 into preset 1. This might be helpful for a
stroboscope preset.
As with most other things in Eos, you can label a palette: Beam Palette 1
Label will bring up a dialog to label beam palette 1.
You can apply a palette on the command line: Chan 1 Color Palette 1 applies
colour palette 1 to channel 1.
You can also recall an entire palette without having to specify any channels
at all: Recall From Color Palette 1 applies colour palette 1 to any channels
which were recorded into it.
