What color is Sherwin Williams Mushroom?
Sherwin Williams Mushroom SW 9587 is a light, muted beige with a soft gray cast and gentle warm undertones. Its low-saturation appearance keeps it from reading overly creamy or yellow, giving walls a quietly grounded neutral finish. In bright daylight, Mushroom can look pale and airy, while lower or warmer light tends to bring out more of its beige warmth. It is well suited to living rooms, bedrooms, and open-plan spaces where a subtle neutral is needed without stark white contrast. Pair it with off-white trim, weathered oak, linen upholstery, matte black hardware, or deeper charcoal accents for definition.

What are Sherwin Williams Mushroom undertones?
Mushroom is a light, very muted neutral with a soft beige-gray overall character. In the supplied digital sample, it leans slightly yellow rather than distinctly pink, green, or blue, though that bias is subtle and should be viewed as a relative tendency rather than a fixed undertone. Sherwin-Williams classifies Mushroom as a Neutral, which fits its restrained, low-saturation appearance. Warm artificial light may bring out more of its gentle beige cast, while cool daylight can make it read a little grayer and less warm.

LRV of Mushroom
Mushroom has an LRV of 57.44% and refers to Light colors that reflect most of the incident light. Why LRV is important?
Light Reflectance Value measures the amount of visible and usable light that reflects from a painted surface.
Simply put, the higher the LRV of a paint color, the brighter the room you will get.
The scale goes from 0% (absolute black, absorbing all light) to 100% (pure white, reflecting all light).
Act like a pro: When choosing paint with an LRV of 57.44%, pay attention to your bulbs' brightness. Light brightness is measured in lumens. The lower the paint's LRV, the higher lumen level you need. Every square foot of room needs at least 40 lumens. That means for a 200 ft2 living room you'll need about 8000 lumens of light – e.g., eight 1000 lm bulbs.
