"If I'm going more towards earthier grays and beiges and slate blues, I'm going to look more towards Sherwin-Williams. With Benjamin Moore, sometimes they have a little bit brighter colors, a little bit more colors that are energized," she said. "So to me, it's a matter of what I'm trying to accomplish as to what paint company I'm going to use."
