Harlequin pattern:  Harlequin pattern is basically a checked pattern, but with diamonds instead of squares. Often, there is a small dot where the points of the diamonds meet. Harlequin can be very colorful, or a simple design of white plus another color. It's a fun pattern for a contemporary, glam, eclectic, or Parisian room.
