Lerp a Grayscale?

I have a grayscale image effect in my scene, and I want to make it so that the effect fades in when I hold Fire2, and Out when I let go. How could I do this? There arn’t really any numbers to lerp in the script.

Upload the grayscale script/shader to pastebin and I’ll show you what variables you can Lerp.

Do a Color.Lerp(Color startColor, Color endColor, time) on your items.
