Something I noticed many years ago while buying cloths or everyday items.
I stand in front of a rack of shirts, whether it be T-shirts,button ups, or a polo & check for my size, I then pass over the nice blue shirt with silver markings & reach for the burgundy or red shirt, with (any color) markings. Although the blue/silver shirt looks very nice, I can never bring myself to wear blue/silver. I have also noticed this when buying 97% of everyday things. Don't get me wrong, I do have a few blue shirts & other blue things, but not many. I would never buy a blue truck with a gray or silver stripe. I like the color blue, but do not want anyone thinking I am a Cowboys fan.
The same may apply for other rival team colors.
Just an observation and wonder if any of my other fellow Redskins fans do the same when buying things.
