Not much of a photo, but a really good example of how colour can change the "shape" or perception of depth in an image. In the mono image the top right of the frame is of no consequence, not so with the colour, where the eye is inevitably drawn to the orange an the little strip of blue in the lower right. My first impression of the colour image is of a shared importance between the hat and orange corner, then a secondary discovery of the blue strip matching the blue pullover and hat (this could be intensified to strengthen it). The mono image is very much about the person, front and centre with the contrast in the hat, texture and tone, as the primary attention getter.
