What does the rainbow flag mean?

Color has always played a very important role in expressing gay pride. In Victorian England, green was always associated with homosexuality, and purple (more precisely, lavender) became a popular symbol of pride in the late 1960s. After the Stonewall riots, a fashionable saying was "purple power". Of course, there is also the pink triangle symbol, although it was originally used by Nazi Germany to identify gay men in concentration camps and became a widely circulated gay symbol after the 1980s. However, the most colorful symbol of homosexuality is the rainbow flag, which combines the colors of the rainbow-red, orange, yellow, green, blue and purple-to represent the diversity of gay groups. There are several totally unrelated rainbow flags in use today. Perhaps the most famous is the flag used to represent "gay pride". In Italy, rainbow flags are usually used as a symbol of peace.
