Not only were the “Color Rush” uniforms donned by the Buffalo Bills and New York Jets roundly criticized for their somewhat off-putting appearance, the all-red and all-green uniforms worn by the two teams respectively also made it extremely difficult for people with colorblindness to follow the action on the field. The NFL has since indicated that it will take the experiences of folks who are colorblind into account in the future.
With red-green colorblindness being the most common form of colorblindness, the uniforms used by the Bills and Jets obviously presented a huge issue to people with colorblindness, the NFL was confronted with an issue it presumably never envisioned.
