SW has COLORSNAP for smartphones
Just to let you know, this must be something new that Sherwin Williams has.
There are several 'snap' applications available for iPhones, like LEAFSNAP and MEALSNAP, but this is the first mention I've seen of COLORSNAP. You can download it for your iPhone, Blackberry, or Androids at the SW website. I'll put in the link below.
Now I'm hoping I can find the LEAFSNAP for Android too, because it will identify plants by taking a picture of the leaf, mostly for northeast plants, but helpful as it expands its coverage.
What a great help these little applets will be, keeping your color pallette on your phone....to carry with you when you shop. If I can crosspost this to DECORATING forum, I will.
