Here are a few of the samples created from the Sherwin-Williams web site. It's kinda fun to download a house photo, highlight the area to be painted and play with all the colors they offer. Of course, not all of the "to be painted" areas were highlighted - so some of the old color shows up here and there -- but you get the picture.
Sample 1 -Current worn barn color
Sample 2 - Gauntlet Gray
Sample 3 - Pewter Cast
Sample 4 - Cityscape
Sample 5 - Mink
I know there's not much difference between all these colors, just subtle hues and shades. I'm off to pick up about 5 pint sample colors -- brush them on and see what works for both of the WE's.
