Willow
What Willow Actually Looks Like
Willow is a very dark, rich brown that sits right on the edge of purple. In warm, direct light it reads as a grounded espresso brown. Pull it into cooler or indirect light and the purple side surfaces fast. It is not a neutral in the way a straightforward charcoal or warm greige is neutral. It has a personality, and that personality changes depending on what surrounds it.
Willow Undertones
The purple undertone is real and it is not subtle under the right conditions. Pair Willow with anything red-tinged, whether that is a red-brown architectural feature, orange-adjacent stone, or warm copper hardware, and the purple cast can become the dominant read rather than a supporting note. In warmer, more isolated contexts it holds as a deep brown. The safest way to think about it: brown is the baseline, purple is always waiting.
Where Willow Works Best
Willow works well as an exterior trim color on homes where the surrounding palette skews warm and tan, anchoring the overall look without fighting for attention. Indoors it reads dark, rich, and enveloping, which suits spaces where you want that kind of weight: a library, a dining room, an accent wall in a bedroom. It is not a color for rooms where you need lightness or airiness. Low LRV means it absorbs light rather than reflects it, so plan your artificial lighting accordingly.
Where to put Willow
On a south-facing exterior with warm tan or neutral siding, Willow anchors beautifully as a trim color, reading as a rich, grounded brown. On west-facing exposures or alongside stone with red or orange tones, sample it carefully first. The purple shift can turn an intentional brown trim choice into something that reads as a mismatch against fixed features like gutters or stone.
A dining room is one of the best places for a color this dark and layered. You are rarely in a dining room under harsh daylight, so the depth works in your favor. Pair it with warm white trim and warm-toned metals to keep the brown reading forward and suppress the purple.
Willow is well suited to a room where the goal is to feel immersed and settled. Dark bookshelves, leather seating, and warm lamp light all complement it. Avoid cool-toned accent colors here, since anything with blue or red in it will pull the purple undertone out.
On a single accent wall in a bedroom, Willow adds serious depth without requiring you to commit the whole room. Keep the remaining walls a warm off-white or warm greige so the contrast feels intentional rather than heavy.
What to Pair With Willow
No formal Benjamin Moore coordinates are listed for Willow CC-542, so pairings here are based on its observed behavior. Because the color reads so differently depending on context, your surrounding choices do a lot of the heavy lifting.

Colors that clash with Willow
Red-brown gutters, fascia, or stone with orange or red veining will activate the purple undertone in Willow strongly. What you intend as a cohesive dark brown palette can end up reading as a purple-and-red combination that looks unplanned.
In rooms with cool gray or blue-toned furnishings, flooring, or adjacent walls, Willow's purple undertone will surface and compete. The result can feel unresolved rather than sophisticated.
Willow has a very low light reflectance value and will make a poorly lit room feel significantly darker and smaller. North-facing rooms with minimal artificial light are a particularly risky application.
Common questions
The color code is CC-542. The LRV is 9.06, which is very low, meaning the color absorbs most light rather than reflecting it back. The hex and RGB values are shown in the spec block on this page.
It depends heavily on context. Against warm tan or neutral surroundings in good direct light, it reads as a deep brown. Against anything with red or orange tones, especially fixed architectural features you cannot change, the purple undertone can become the primary read. You need to sample it in your actual space and against your actual fixed elements before committing.
If Willow consistently pulls purple in your specific context, look at Benjamin Moore Dragon's Breath 1547 as a comparison point. It may give you a similarly dark, rich result without the same purple sensitivity, though you should still sample it against your fixed features before deciding.
Yes, Benjamin Moore makes it available in both interior and exterior formulas. Its behavior in each context is different, and the exposure of your exterior surface matters a great deal. A south-facing application in warm light is a very different situation from a north-facing or shaded exterior.
For interior walls, a matte or eggshell finish will give you the richest, most absorbed look and minimize any sheen that might flatten the color. In higher-traffic areas or rooms where you need washability, an eggshell is the practical choice. Avoid high-gloss on walls, since it will make the color read differently than you expect at this depth.
