Premier League teams have blundered again by choosing kits that make the two teams indistinguishable to up to 100,000 TV viewers.
The latest mismatch came between Sheffield United and Chelsea, when the teams met at Bramall Lane on Sunday, in a game televised on Sky.
Chelsea ran out 2-1 winners, but colour-blind fans were the losers, since the red and white of the Blades’ shirts merged with the 'arctic blue' of Chelsea's second strip.
Viewers immediately took to Twitter to complain.

Well done #ChelseaFC.
