Join Angie Taylor for an in-depth discussion in this video Making colors change over time, part of After Effects Expressions for Premiere Pro Editors.

When I look at the graph that's created by that expression,…you'll see that I'm just getting whites and grays…in my colors, which isn't really the result I'm looking for.…Why do I get whites and grays?…Well, first of all, to give us a clue,…let's look at the expression.…Now, it's created a variable, the word temp,…and it said, "temp =" the result of our…audio amplitude keyframes.…And then it's made four values in an array,…and each of them is the same.…
Now, the problem is, these values represent…red, green, blue and alpha.…
