An official flag was formally adopted by Rotary International at the 1929 Convention in Dallas, Texas. The Rotary flag consists of a white field with the official wheel emblem emblazoned in gold in the center of the field. The four depressed spaces on the rim of the Rotary wheel are colored royal blue. The words "Rotary" and "International" printed at the top and bottom depressions on the wheel rim are also gold. The shaft in the hub and the keyway of the wheel are white.
