My opinions on interior color selection
We put an offer in for our buyer on a newer mid century modern home. She is a wonderful woman with a great taste in art. Her current home is light and bright, adorned with colorful artwork, pottery and hand blown glass works. Her potential new home has a white on white color scheme on the interior. White walls, ceilings, doors and trim. I never thought I would say this, but I absolutely love it! I realize that the simple color scheme is elegant and doesn't compete with the beautiful wide plank natural oak flooring and dark wood cabinets. The light and bright wall space will provide a great backdrop for all of her artwork.
In my former life as a general contractor, I had painted many, many homes. Over the decades I've seen all sorts of trends come and go. I've painted almost any color you can think of and I've always, against better judgement, painted what the clients have wanted me to. I've given hundreds of paint color suggestions also. What is noticeable is how my taste has evolved over the years. Feature walls became feature rooms and usually evolved into a different color in every room and even multiple colors in one room. I've left jobs with 16 different paint colors in the past. There is nothing wrong with color, or peoples opinions, especially if they're happy. I began to observe my color suggestions become more and more subtle colors.
I will share this one thing that I had learned. It instantly changed the way I thought about color on interior walls. I was doing a remodel and we opened up the kitchen/dining/living areas into an open concept. Large windows around the perimeter allowed you to view the natural scenery outside. I was told that if you paint the walls a darker, bold color, your eyes stop on the color first. It makes it hard to look past the walls and see the scenery. If the walls are a more subdued color, your eye naturally looks out of the window. This does a few things, it makes the interior feel more spacious and invites the outside in. I did an experiment and volunteered all of the sub contractors, homeowners and neighbors to participate. The response was clear. It held true throughout everyone's comments.
Long story short, in my opinion, most people are happier with a light color scheme accented by colorful artwork, furniture, pillows, etc.
