Actually, not even: if you've ever looked at the "negatives" used for
analog black&white photos you'll surely understand that inverse-video
doesn't work so well for images (mostly because it inverses lights and
shadows, thus confusing the semantics).

For a "pure" text or other such circumstances where the colors don't
carry much meaning, it's not too hard to do something like "inverse
video" with an acceptable result, but for photos or comparable kinds of
images, I suspect that it's somewhere between very hard and impossible.
