Who says that you have to stick with a paint colour once it's on the wall?

After having the contractors paint the living room "Glazed Green", the inevitable happened. We went to cousin Mary's, and her pale greyish-blue paint colour (which we've seen whenever we go there, for at least a dozen years now) looked sensational, all of a sudden. So, Monday morning dawned with a colossal scramble to the paint store to a) find a new paint colour, b) buy a new gallon of paint, and c) rush it over to the house so as not to cause the reno to fall behind schedule. The new colour is "Silver Cloud", Benjamin Moore 2129-70, and it's quite lovely.
