A bold “C” of red encircling a golden disc, set against stripes of blue and white. The colours speak of sky, snow and sunshine; the red earth anchors it. Few state flags are so modern and instantly legible, Colorado wears its landscape with graphic flair. Colorado’s flag is a simple yet powerful design, adopted to reflect natural beauty and the state’s centennial admission.
