xxdeadmonkxxrecently wrote a comment under my stream that 'black background makes you feel very special in roguelike games, more fantazy than in common graphical RPGs'. It's gaved an idea to me: what if in certain character states (like 'stun' or 'hallucination') game would make your window screen colors inverse - like a negative in photogaphy.

It wont blink, like at this picture - this state would just appear right after you got in certain state and would stay the same till it would be lifted - so it would't be irritating,
It would make game pretty unusual in such state
