Why do the rendering clouds in PS only have a black circle?

It may be the default value of "black and white" on the ps interface when using filter image processing.

So when you are finished you will see that the rendered image appears to be a black, white and gray image.

The problem can be solved by entering the appropriate foreground and background into the color palette in PS and then rendering.
