The original pride flag flown at the San Francisco Gay Freedom Day Parade in 1978 had eight colors. The eight colors represented different concepts such as sexuality, life, nature, art, harmony, and spirit. The colors were hot pink, red, orange, yellow, green, turquoise, blue, and purple. However, the hot pink color was dropped from subsequent versions of the flag due to the cost of producing it and the difficulty in finding the fabric. The flag is now commonly recognized as having six colors.
