Expression to constantly change color of a spectrum
Hi,
I’m running a music channel where I upload music regularly, and I need an expression for the color effects on my audio spectrum layer (Inside Color/Outside color)
Basically, I need a way to keep this spectrum constantly changing in a rainbow form, if not I can put in my own colors if needed, if you don’t understand what I mean look at the spectrum at the back of the black spectrum, I need an expression that can do that. https://youtu.be/ZaViSUC6mnQ
Thanks In advance! -

This might be a place to start:
hues = [0,30,60,120,180,240,300];
freq = 1;
idx = Math.floor(time*freq)%hues.length;
hslToRgb([hues[idx]/360,.85,.4,1])Dan

Yes, it’s something like how I want it to be.. Thanks alot! But question.. is there a way to modify the expression to make it change a little slower?

To make it go half as fast, change this line:
freq = 1;
to this:
freq = .5;

Isn’t there a way to make the colors smoothly blend?
