I have made mist in my scene,and it works great when it's white mist, but if I try to darken the color, I get all sorts of strange colors appearing in the background of my scene. How do I make the strange colors disappear?

Render Layers > Map Value, Render Layers > Mix, Map Value > Mix > Composite

My node setup

Withough Mist

My scene without mist

White mist

Light Mist

Dark mist with weird colors
