Is the second law of thermodynamics routinely violated?

Very well, so the observer can still distinguish between the color of the left box and the color of the right box after you have removed the wall separating them. I still assume he can only see the solid color of each box - he sees the entire left box as one color, and the entire right box as one color too. In that case, I predict he will likely see a never ending fluctuation of monochromatic colors. It is possible but highly unlikely that he will see a solid color in either box, unchanging over time. More probably, the color of each box will usually be a middle shade of grey, constantly flickering from lighter to darker tones. Eventually both boxes will return to their original black and white, if only for a moment.
