Some may say new color

Or, some may say turning on/off light (which is actually false).

Keep it real. Seriously.

Nothing. You can convince yourself of anything.

The OP's question asked what is impossible to do IN a lucid dream. Not what is possible during a lucid dream that would then turn out to be impossible when carried over to waking life.

The laws of physics you can break.
The laws of reality are a different matter...
Like I said, you can't acquire radically new information you've never been acquainted with before (e.g. college calculus), but you can use a dream to try and make connections or otherwise "get" the subject material.
Along the same lines, it would be impossible to become omniscient, or all-knowing. There is simply no way you could tune yourself into every little pebble on earth, etc.
It is also impossible to visualize a new color, because you haven't been acquainted with it. You could try to imagine what it would be like to see infrared or other wavelengths, but nothing new can come out of the known spectrum of visible light.
