Produces colors using rainbow spectrum patterns.

There are several spectrum types to choose from which balance the colors in different ways.

The field will produce a color based on either the Wavelength parameter, or values from the wavelength input field.

Parameters

Name Description Regular Handling Read-Only Handling
Wavelength

Constant value to use as the wavelength to map to a color. This is only used when there is no wavelength input field.

 Runtime Baked
Wavelength Unit

How wavelength values should be interpreted.
