Family Room - I like the white painted brick and the three white vases (?) on mantel along with a variety of colors of books with their covers removes.
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.
