At the Behr paint website: http://www.behr.com/behrx/workbook/
for only $4.95/year, you can take a photo of the room you want to paint and see how it would look in whatever colors you are dreaming of, before you ever wet a brush!!! How cool would that be???
I know it seems like a lot of my friends are moving into new places or really re-doing their current homes and this would be a marvelous tool!!! Check it out.
