In an email to The Associated Press, the league said Friday the NFL will incorporate a colorblindness analysis when designing monochrome alternate team jerseys for next season.

The league was responding to concerns raised by fans who had difficulty Thursday night distinguishing between the scarlet red Bills and Kelly green Jets.

Various studies have found that red-green color blindness is the most prevalent and affects between 10 million to 13 million Americans.
