What is Two-Tone in Poker?

A board with exactly two different suits, meaning there is a possible flush draw. Two-tone is usually used to refer to a flop that has two cards of one suit.

Example: 8♠ 6♠ 2♦ is a two-tone flop, as is A♥ K♥ 7♣.

Other types of boards include rainbow (all different suits) and monotone (all the same suit).
