The Kansas City Star is reporting that Sporting KC will go "retro" next Wednesday against the Colorado Rapids to commemorate the 20th anniversary of the club's first match.
Sporting Kansas City will reportedly go retro when they host the Colorado Rapids next week, bringing back elements of their famous (infamous?) rainbow kits from the mid 1990s.
The Kansas City Star has photos (linked here) of the kits. Sporting KC will wear warmups that highly resemble the kits shown in the photo above, and for the actual game will wear their alternate white kits with the rainbow infused into the numbers.
