The Indiana state flag has a dark blue background with a gold flaming torch surrounded by nineteen gold stars. The torch in the center stands for liberty and enlightenment; the rays represent their far-reaching influence. The official description in the Indiana Code explains the rest of the symbolism: "The field of the flag shall be blue with nineteen stars and a flaming torch in gold or buff. Thirteen stars shall be arranged in an outer circle, representing the thirteen original states; five stars shall be arranged in a half circle below the torch and inside the outer circle of stars, representing the states admitted prior to Indiana; and the nineteenth star, appreciably larger than the others and representing Indiana shall be placed above the flame of the torch."
Indiana flags for outdoor use are constructed of a durable nylon fabric especially developed for flag use. Nylon's tight weave provides maximum beauty and flyability as well as brilliant, fast colors. Its weave helps shed pollution, dirt and grime that the looser weave alternatives absorb. Nylon is water repellent and mildew resistant.
