Jennifer Jones of Niche Interiors in San Francisco says, "We used teal in this project because it really pops against the white moldings and light floors. It's a bold, happy color that pairs well with neutrals such as gray, taupe and tan." I second that.
I love how you can use the various shades of blue especially teal in so many versatile ways. You could decorate an entire house using just teal and these pictures have shown how to do that but still make each room fresh and different.
