When you say "invert", do you mean that you literally want every color on the screen to be inverted? Or is your desire that everything on the system actually reflects a different color scheme in the screenshot? Because those are different things.

I meant, I would like to have it look like the normal standard them. Did not know how to express it differently. My main reason is that in screenshots, black background with a white font does not always look suitable.

Thanks. I don't think this is something we'll be able to do, sorry. A screenshot should reflect the actual state of the system; if that actual state isn't good enough, then it should be changed beforehand, or in post-processing afterwards.
