This is for the client that would like help deciding on color schemes for the rooms of their home. So many people are unsatisfied living with white walls, but are unsure of what to do instead, or they are afraid that color would be overwhelming. Gretchen explains to clients that when you have white walls, the contents of the room (furniture, art, etc) can stand out in contrast and seem separate... while color on the walls provides a unifying effect and brings together all of the similarities of tones, making the interior "flow".
