The uni-verse has had a bit of a blast from the chromatic past lately. First, the San Jose Sharks announced that they'd be wearing teal at home during this season's NHL playoffs -- a change from their previous four postseason appearances, when they wore black. Then the sports world was awash in purple as a memorial tribute to Prince. And just a few days ago, the Sacramento Kings unveiled a set of logos featuring a new, deeper shade of purple.
If all this left you feeling a bit of déjà vu, it's probably because those two hues -- purple and teal -- evoke a very specific time period in sports design.
