color wave: I looked and looked for a palette that matched the beautiful colors of the Caribbean the first time I saw it as I drove up to the ruins of Tulum along the east coast of the Yucatan peninsula of Mexico. This is the closest I found but it still doesn't capture the intensity and beauty of the colors of the sea.
living room walls...lighter aqua...Sofa in a light gray solid. Additional upholstered pieces using the darker blue as a base color, but a print or pattern. Some woods painted black with an accent piece or two of darker blue. Black picture frames, with blue lamps. Lots of pillows and I would definitely throw in some yellow and white here or there - as long as it doesn't come across as too busy.
