"Lipstick" for doors has become a signature of 2LG Studio. In their own home, where they came up with the idea, they used a bold, bubblegum pink color around the doorway in the kitchen. "The pink feels right in our home as our hallway was painted this color when we first bought the house," they say in the book. "How vibrant is that color? We couldn't resist—the pink told us what it wanted us to do with it."
