It isn't always the amount of orange used that creates the impact. Here a small dose of orange print goes a long way when seen on a chair from Anthropologie (with personality to spare) and placed against dramatic gray walls.
Over the years it has become more acceptable for your home decor to call from many different styles and eras, and with the growing popularity of sites like The Selby, traditional homes have experienced a renaissance with the contemporary and modern set by pairing old with new. Painting all wall details the same color updates traditional moldings.
I'm almost always in favor of painting moldings and casings the same color as walls. I'm also a fan of matte paint in general, but especially when all the decorative trim is painted in. Don't worry; matte paint is just as wipeable as eggshell but doesn't have that rental-apartment sheen so many of us are familiar with.
We often see wainscoting and walls with contrasting paint colors, but painting it the same color as the wall has a wonderful effect. It's far less busy and can help spaces with low ceilings feel a little higher, where the white meets the color.
