DIL loves purple and I went and pulled all the purples in my stash. I must have 20 purples with only 2 that match. Red purple, blue purple, gray purple and all the shades in between.. Don't get me started with reds -- pulled a bunch of reds for a Christmas quilt and I decided my stash is too big because there were so many shades of red. DH had a car that was called "sea mist green" but to me it was teal blue. I have a pretty good eye and if I want to match colors I can do it but the paint chip idea is great -- as long as both of you are using the same set of paint chips.
