I went out for a cheesy one day sale tonight, just to see if there was anything decent. I ended up finding a really cool sweater, for $20. So I picked it up, got home, and discovered that the actual color barely matches the color it appeared to be in the store. We have similar lighting to what's at the store in my kitchen, and it looks right there. Any other room in the house, and it's changed colors.
It seems like a truly remarkable fabric, in that sense, but I'm rather annoyed that it isn't the color I thought it was. ;-p
