Known for her passionate love affair with color, French interior designer Sarah Lavoine lets us take a peek into this fabulous Parisian duplex she designed. With a black and white base color palette, Sarah introduced strokes of jewel tones to create a sexy design story. I'm sure she decided to paint the floors white to make these gorgeous colors pop and really come alive. Her masterful mix of furniture styles has the right proportion between old and new pieces. I'm in love!
