Rainbow Frequency (F) - Move right to make the multicolored 'rainbow' pattern change color more rapidly in the Primary Spikes Primary Spike Rainbow Frequency Control

Click the control or press F to activate.

The Rainbow Frequency control, part of the Primary Diffraction Spikes control group, sets the rate at which the multicolored "rainbow" pattern repeats. Optically, higher focal length systems generally produce a more gradually repeating pattern, and you can use this control to closely match optical results.

Higher Rainbow Frequency values make the colors repeat more rapidly.
