A rich, grown-up relative of aqua, this dark greenish-blue color looks best when paired with warm neutrals. For the office, consider accenting a teal skirt or blouse with brown, crimson or gold. Feeling bolder? Slip into an iridescent sheath with black platform heels. As for finding the best hue for your skin tone, that's simple: Teals that are brighter complement light complexions; those with a deeper tone work on dark skin.
