    LCD screens have a light behind the screen that is always on, so white is usually the most efficient color to produce; you just let the light shine through. Black on the hand requires the light to be completely blocked, and this takes energy. So, on the face of it, white would always be cheaper than black to create on LCD screens. Turns out this is mostly true, and on average, takes less than a watt of energy to do.
