Change color of scene.background == CubeTexture

Is it possible to somehow change the color of the scene.background == CubeTexture? I want to apply fog color to background.
The only idea that comes to my mind is to replace scene.background with skybox mesh etc, everything is easy then

Yes, you can apply a cube texture to Scene.background. The official example webgl_materials_envmaps does this if you need a code template.

Question is how to change color of scene.background == CubeTexture
I already have background with CubeTexture)
I came to conclusion that the only option is to set scene.background to null and add skybox to the scene and then change skybox.material.color to color that i need
anyway thank you for your response!
