My friend, Julie, as always, came to the rescue. I don't know what it is about color that totally intimidates me. I become paralyzed from my inability to narrow the choices. She picked the colors. Julie has the most wonderful - and natural - sense of aesthetics. She understands my taste better than I do myself. She listens to what I'm trying to accomplish and without any seeming effort, comes up with the perfect solutions!
It is so much fun to watch her in action. At Home Depot, Julie found the color match for the mosaic tile right away and once she saw that I was happy with it, set about finding the trim color from among hundreds of shades of white. A few times I thought she had found it, and I nodded in agreement, only she wasn't satisfied, nope, not my Jules, she kept searching (and playing) with the color chips until the perfect shade emerged, and indeed it became apparent that no other shade of white would do.
Thank you, Jules! Thank you for lending me your talent, and for your endless patience in putting up with this cantankerous friend.
