I don't know about you, but when I am in a store and I see something I like for a particular room and am thinking of purchasing, I am never sure about the exact shade of the particular color of pink, for example, in my living room, or blue (is it a grey blue or a green blue? I don't remember!).
Here's what you do, grab some paint swatches from your local hardware store and cut out the colors that are your color scheme (for each room if you want). Make sure that you label shade on the back what room its for. Then keep these in your wallet or punch a hole in each and put them on a key ring and - presto! No more taking back that sage green that should have been a celery. :)
And when its time to do some touching up, you already have your paint samples. :)
