You may opt to keep all your ornaments in the same color family, or you can create a multicolored masterpiece on your tree by mixing and matching. Some popular ornament color combinations include black and white, red and green, and jewel tones like purple, navy, and green. Red and white ornaments can be combined and tie in nicely with candy canes, too. You can mix and match colors, or you can choose one hue and deck your tree in it from top to bottom.
