Yay! I can help with this one! Revere Pewter is the color our living room was painted by the previous owners. I found it too light to really feel like a "color." DH was surprised to hear it wasn't white. I painted over it in Pashmina, which looks beige on the swatch but much greyer in person. But, my absolute favorite BM color is my dining room, which is Cotswald. It's more of a warm beige, but I love it. I'll try to post pics.
