First, buy some paint chips.
Then, buy some more.
Then, when you have it narrowed down...
Go purchase a sample for $5.
Realize it's wayyy too bright. Go buy some more samples...
Still a no-go. Go buy one more. Except this time the guy at the paint store gives it to you for free because you have been there so many times.
Finally find the right one. Then realize that if you don't paint tomorrow (Sunday), you will have to do it during the week (which isn't easy). Or do it this weekend. Oh yeah, you will be out of town, duh. Ok. Next weekend. Oh yeah. Out of town then too. Whoops. My wall might look like this for a looonnnng time.
