Not an everyday item, true, but this painting is what came to mind when I started to think about manipulating color schemes for the ds106 exercise.  Cockfight is an original painting by BVI artist Joseph Hodge. The first frame is the original version of Cockfight.  I used picnic in Flickr to create the blue and the red versions.  There is so much movement in the original painting, that even the cool blue version conveys high energy.
