I've bought plenty of stuff where the color wasn't quite right, including a used car in light blue (which I got a great deal on). I figured I would get used to the sickly, silvery shade, but I still hated the look of the car when I sold it five years later.
Hard to change a car color, but clothes? I had a closet full of "not quite right" colors (of course, I got a great deal on those too..).
It started with the lab coat hanging in my closet. A white summer jacket that only needed a mixture of "taupe" "cocoa brown" to put it back in rotation.
Then I got caught up in the alchemy of it all... I bought 6 bottles of liquid dye and started mixing... throwing perfectly good stuff in with the poor choices. The result? Instant gratification. Completely different colors and fabrics now go together because they're the same tonal family.
I was ready to throw sheets, beach towels, tablecloths into the next batch. But the obsession ended when my top loading 19-yr old washer died. At least it went out in style.
