It's not a dumb question, it's a dumb phrase.
I remember in the early days of TV shopping, HSN hosts used to use the phrase "buyers remorse", to suggest if you pass up an item, you will regret it. That always struck me as a ridiculous thing to say, because as I know it, buyers remorse means that you regret having purchased something. They used that phrase regularly. I don't watch HSN very often. I wonder if they still say that.
In any case, "colorway" sounds like something a five year old would say, but then, is it as bad as "pork chop pockets"? Oh, dear.
