Designer kelly wearstler has several books that I often reference- Modern Glamour and Hue (available on amazon). I like her mix of colors and textures and her attention to detail. One of my favorite spaces designed by her is the restaurant BG at Bergdorf Goodman. Above is an example of how she incorporates color through details at a residential home. She starts with basics and builds from there- white walls, a dark floor, select pieces of black furniture, but then layers in coral /peach upholstered stools, accessories, a gorgeous coral painted door- it all comes together effortlessly and her designs are absolutely stunning.
If your budget doesn’t allow for custom upholstered stools or furniture, you can still change your home rather inexpensively with paint. Try painting your door or a piece of furniture a color you love. Note that the finish can make a difference- Kelly put a gloss finish on the door pictured above which reflects a lot of light. (I painted all my 2nd story doors to the bedrooms and guest bath navy and I love it.) If you have a white room, add flowers, a few pillows or a throw in this color palette and it can make an impact even without painting.
