Hex Color Numbers and Document Invert Inversion: Making backgound black and typeface white

HI Kami! I can’t find any way to invert the colors on a document so the background becomes black and the typeface becomes white. This is a very useful feature in classrooms when we are using projectors but the room is not darkened. Does Kami offer this feature?

Has there been any thought given to this idea? It would be so great if there was a way to toggle the background dark and text a different color. I personally find it much easier on the eyes. I read all my eBooks this way.
