Change sky color

I've seen a few shaders such as the rtgi and fog removal shaders that can detect the sky or have an option to ignore the sky in their effects. I was wondering if it would be possible to detect the sky's color then change only it's color. In games like AC Origins and odyssey the night sky is rather bright and I'd love to make it darker for a better nigh time atmosphere.

Don't know if these shaders do something else besides check the depth buffer, but you could try to use a depth mask and a color mask to apply a shader that shift the HUE of the sky.

You can use CanvasMask and ColorMask from my repo and this to change the HUE.

Hope I could help.
