Love the revere pewter! I am about to paint my living room the same color.
I have had lots of success with Revere Pewter too – in a dining room, my son's room, a hallway, a master bedroom… It seems to work in many different lights and I love the subtle colour. Good luck!
The pewter is lovely – I think it will be so fresh and calming in there!
There are several ways I have gotten the color I want.
1. pick a fabric color. A paint store can match in their machine.
2. You can buy those small bottles of acrylic paint at a hobby store, cheaper than the samples at the paint store. Mix them to the color you want. Paint on a paper plate and take it to your paint store.
3. I have matched paint color to furniture by taking the arm cover to have it matched.
good luck j
