Teal has always been one of my favorite saturated jewel tones. Used in large doses like on walls, a sofa, or rug, it can act as a foundational neutral in a space, a lot like navy blue does. So if you're looking for something just a bit less predictable than the ubiquitous grey sofa (not judging, mine's gray), maybe give teal a try!
And look how great a little dash of citron or chartreuse looks in these spaces ... it's an invigorating color that really wakes up a room. (It happens to be the a main accent color in my design studio, too.)
