To avoid a kit clash, the Billy Goats had to come up with a seventh make-shift strip against RB Leipzig
Cologne's home kit is red and white, while their away strip for 2017/18 is... erm, red.
So, to prevent a clash with the white-and-red of Leipzig in their 2-1 win on Sunday, the visitors wore a black shirt with matching shorts – bizarrely, the seventh different kit they've worn this campaign.
Clubs traditionally have three kits for a season (home/away/third), but Cologne's additional commitments mean they have worn a further four.
The Billy Goats have a special Europa League home kit, a one-off retro top and now an emergency black strip. In September, they turned out in their 2016/17 third kit against Augsburg, which makes their total seven.
The shirt donned against Leipzig is the only one which can't be bought from the club's official website, but the other six can be yours for just £422.
Kit manufacturers Erima have been kept very busy indeed, but the relegation-threatened club have opted for Uhlsport from next season so will be able to start all over again with some fresh designs. Lovely.
