I had found at a yard sale from my parents' condo a box of really nice blue and grey/silver tiles. We fell in love with them, so we decided to use their color to finish the bathroom. That was harder than you might think. After many unsuccessful and frustrating trips to Home Depot, I was convinced to go to Sherman Williams. I hit their store at 6 o'clock the next morning, and explained to the gentleman there that not only was I trying to match this really hard color, but if possible I needed the paint today, since the parents were coming to visit that weekend, and we were hoping to have it all done.
The people there were fantastic. Not only were they able to match the blue perfectly, they got it done in just a few hours. I have no idea what goes into paint matching, but to give you an idea - the tiles were most definitely blue, except when you put them next to paint chips, the ones that matched were purple. The paint the ended up mixing for us is actually designed for automotive work, it's purple when the light is directly on it, or when the paint is thin, but other than that it is the most amazing deep blue you've seen in a while.
