the rainbow flag has found wide application on all manner of products. the rainbow flag colors are routinely used as a show of lgbt identity and solidarity. the rainbow colors have become so widely recognized as a symbol of lgbt pride and identity that they have effectively replaced most other lgbt symbols, including the greek letter lambda and the pink triangle. one common item of jewelry is the "pride necklace" or "freedom rings", consisting of six rings, one of each color, on a chain. other variants range from key chains to candles. in montreal, the entrance to beaudry metro station, which serves that city's gay village, was rebuilt in 1999 with rainbow-colored elements integrated into its design.
