I'm reminded of an old Calvin and Hobbes cartoon where Calvin's dad explains that color really WAS invented in the 1930s. Before that, the whole world WAS black and white, with shades of gray, but when color was invented it changed to color. Calvin asked why the old black-and-white photos were now B&W and not in color; his dad explained that prior to the change to color they had been, but when everything B&W turned to color the color pictures all turned to black-and-white. Until, of course, Calvin's mom interrupted....

Heck, it makes sense to me!
