Anne DeCocco I think that's a creative mind at work! It looks like a chandelier that you might find in many stores. What makes it unique is that the homeowner didn't put shades over each light bulb. So the bulbs become part of the design. Wonder if those are regular bulbs or Edison bulbs, which would give it even more interest when the lights are off. I'm loving it!
One terrific way to include many different colors of the rainbow into one space without overwhelming the space is to use books to create that color. Choose an array of books that includes jackets with each color of the rainbow and display them on a mantle or shelf. I love the way that the table and pillows here add additional color to this display.
