The rainbow patch on NFL jerseys is part of the Crucial Catch program, which is a partnership between the NFL and the American Cancer Society to raise awareness and funds for cancer screenings in under-resourced communities. The rainbow is meant to represent all types of cancer, with each color representing a specific type of cancer, such as red for blood cancer and lime green for Non-Hodgkin lymphoma. The NFL has been working with the American Cancer Society since 2009, and each season, each team in the league has a designated Crucial Catch game, which is used to spread awareness and raise funds for cancer screenings. The multicolored gear worn by NFL staffers and players during these games includes helmets, wristbands, sideline hats, and quarterback towels, among other items. The revenue generated from the sale of these items is forwarded to the American Cancer Society to help fight cancer and fund research further.
