Decorator's White (CC-20) is a cool white paint color, with a slight drop of gray. It is a great choice for trim, doors and moldings.
Are you looking for a white paint color that's white, on the cooler side but not stark white? Decorator's White is one of Benjamin Moore's truest whites with just a hint of gray and is one of the most popular white paint colors.
Decorator's White Trim
Decorator's White is a great choice for trim and moldings because it never looks cold and stark or too warm, no matter what wall color or room exposure it's paired with. That's exactly the reason we chose it as our trim color for our entire house. It look like a "white-white" but you don't need to worry about it looking too cold or too warm.
However, put it against a brighter, starker white like Sherwin Williams Extra White or Benjamin Moore's Super White and you will instantly see that slight gray undertone coming out. In fact, next to a very bright white like that, it looks like a dirty white! Don't worry, it doesn't ever look dirty under normal circumstances, just when you see it side by side like that!
If your home has an abundance of really bright light (the vast majority of homes do not fall into this category) than you may want to consider a slightly warmer white, like Benjamin Moore Simply White. However, in my experience, Decorator's White looks great everywhere!
Painting Both Walls and Trim
If you're going for bright white walls and need a trim to coordinate, I'll let you in on a designer secret - use the same paint color but use matte or eggshell on the walls and satin or semi-gloss for the trim. Because of the difference in sheen, it won't look like the same color but you won't have to worry about weird undertones!
Decorator's White is also a great white cabinet color and will be my top contender when we eventually remodel our kitchen!
If you are looking for a bright white that is not jarring or stark, then Benjamin Moore's Decorator's White is the perfect white for you.
