Back when I was more into hockey (in the early 1990s, I think?), w/ season tickets to a local minor league team, home teams wore a white jersey with colored accents. The away team wore a solid colored jersey, w/ accents in the team’s secondary color. I fell out of watching hockey for many years, and only recently started trying to pick it back up. But some time when I wasn’t paying attention, they went and switched the standard: Now home teams wear colored jerseys, and the away team wears white. To me, this is bass-ackwards, and can result in me accidentally cheering for the wrong team if I’m not paying rather close attention. When did this shift occur, and was there any particular reason for it?
This is an old article, but it looks like the 2003-2004 season is when the switch happened.
In the league my team plays in the home team wears white/light colored jerseys and the away team wears dark jerseys. But then at a certain point in the season they switch and the home teams wear their dark road jerseys at home. I think they switched last month.
IIRC it was about 1970 when the NHL first required home teams to wear white. I remember as a kid a friend had a New York Rangers yearbook which mentioned this and published all photos of the Rangers wearing white so the home fans would recognize them better. Apparently the reason at the time was teams on the road found it a problem to get white jerseys cleaned. Nowadays jersey sales are a huge chunk of revenue and the league is more interested in having fans buy jerseys… and the white ones are harder to keep stain free. The fans want to wear what the home team wears so hence the switch
