A color palette can be inspired from anything. Look around and you can find inspiration most anywhere- from nature, a unique colored glass, a package or label, or even materials found around your own home. My stone fireplace in my bedroom with a wood beam mantel inspired the color palette in my master bath. I have two old ornate ceiling tiles leaned against the stone wall on my matel that I found at the old 26th Street antiques market in NYC years ago.  The panels add even more texture and the creams in the square panels break up the heavy gray stone wall and lighten it up a little bit.
