what are the nfl color rush uniforms for

The NFL Color Rush is a promotion done in conjunction with the National Football League (NFL) and Nike that promotes "color vs. color" matchups with teams in matchup-specific uniforms that are primarily one solid color with alternating colored accents, primarily airing on Thursday Night Football. Introduced in 2015, the intention was to create a pronounced visual contrast between the teams on the field, resulting in a visually stunning spectacle for viewers. The Color Rush uniforms are specially designed alternate uniforms worn by all 32 NFL teams during select Thursday Night Football games. The uniforms are primarily one solid color with alternating colored accents, and the pants and jerseys are of the same color. The shoes and socks are also matching colored. The promotion was discontinued in 2018, but most teams have continued wearing their Color Rush jerseys a few times per year.
