"My yellow door brings sunshine into my house year-round," says designer Charlotte Hedeman Gueniau. Also upbeat: the mismatched pair of patterned rugs. It can be tricky (and expensive) to find a rug custom-fit to your space, but a couple of smaller rugs does the job. For a yellow door: We like Valspar’s Golden Delight, $31 a gallon, or Pratt & Lambert’s Barleycorn, $22.99 a gallon. A high-gloss finish is rich and easy to clean.
