Growing up, my mother always told me that she liked colors that were laced with a heavy dose of gray. Her mother was the bright and sunshiny type, and like most teenagers she rebelled with her choices of gray and neutrals. They are her warm blanket and by proxy, they often are for me as well.
Do you remember the colors in your parents' house? Are they still comforting to you? I don't think I want every surface in my home to be gray (sorry mom, you did it quite well though!) but those colors will always feel like a big blanket around my senses when I need a pick me up.
Do your interior color preferences echo or oppose those of your parents?
