Despite what some idiots say, it's been a nuisance for a long time. When I forst started going to the Goldstone, more than 50 years ago, I was amazed at how many other teams in the league played in all yellow!
My dislike hardened in the 80s, when we were in the 1st. Division - away to Bolton (white shirts, black shorts, but they changed to all white on the day). Brighton (all blue in those days, changed to all yellow). Then they televised it - on black and white TV!
Now, so often, it makes no sense to change kits. Though I fully expect there are some muppets around who enthusiastically bought the 2013 third choice (or whenever) kit.
Get over it you wuss! My Nan watched snooker on her b&w telly right up until the 1980s and never moaned once. (Not actually sure though she had any idea what was going on.)
