So, with regard to how to choose the right white paint and the light, this is an amazing question that deserves a detailed answer. But, here’s the thing—the white that I have will most certainly not work in every space.
Windows and light is the largest factor to consider when choosing a paint color. Not only does the size of your windows affect how the color is experienced, but it’s also the direction of the natural light streaming inward, and what sits outside those windows, too. For example, if there is a lot of greenery outside it will read differently than say if you’re on the coast where surrounding tones are more muted.
From the artificial lighting to your décor choices, what’s within your space also has a direct impact on the white hues you choose. For instance, if you have a red rug, this will absolutely cast a pink hue onto the walls of the room. Whites are soooo sensitive. You can choose the perfect white paint in the shop, only to find it’s a different color on your wall at home thanks to the constant reflecting and refracting of the light and colors in the space around it.
White will absorb everything and anything in its path.
So, you really do need to get a small sample and try painting a 2’ x 2’ section of your walls first. And not just one wall—a few different walls that get sunlight from varied directions is ideal. A perfect example of this is in my Amagansett living room that has a ton of windows and high ceilings. I wanted a warm white but everything was reading too creamy. Finally, I found the perfect fossil hue but when I painted that same color on my kitchen walls—it has a lower ceiling height and fewer windows—it read a horrible yellow and photographed even worse!
My advice is to look at a range of colors from Farrow and Ball or Benjamin Moore, get out your paint roller, and give it a test on a few walls, checking it at various times through the day—morning, noon, and night. I would also suggest photographing the wall too. For me, that is always super helpful. You may originally be drawn to a warm white but in your space, a cooler one with hints of gray may read just right. You just have to paint, test, and play until you land on the perfect shade.
Also, for everyone who says I have the “perfect white” on my Instagram, know that I color correct my photos a ton, haha! So, the white you see is usually brightened and cooled down, and has contrast added, etc.
Use your own home as your best case study—it will reveal precisely what you and your room needs!
