This tutorial is created because some RGB fixture only have the RGB channel and no macro / effect channel where it is possible to generate a rainbow effect.
Additional FreeStyler don’t have a function that generate this direct.



To do this it is necessary to create a sequence with 6 steps.
All 3 color faders are to be set to fade.
The RGB values are to be as follows.

The sequence will when it is played-back fade from one color to the next.
It will start with red and fade to yellow with all the shades in between.

Looking on the selected fixture in FreeStyler it will only show final color red, yellow and so on.
The shades / rainbow effect comes from the fading in between the colors.
