I believe that frequencies of colors stimulate parts of the brain and that the stimulation evokes associations in the subconscious, part physiology, and part experience. The black and white image largely avoids creating these type of reactions to color, and so displays shapes, forms, and textures devoid of these stimuli, and so those qualities become the stimulus, without distraction.

A color image is more complete, and covers a broader range of visual inputs, and has the power of our reaction to colors along with the pattern and texture contained within.

B&W is distilled, and concentrates on a narrower range, wielding a smaller tool set, but using what it does have more powerfully.
