Sherwin Williams

Undercool

SW 6957

Undercool is a medium-light blue from Sherwin-Williams with cool undertones and a noticeable clarity that keeps it from reading as gray. At an LRV of 49, it sits near the midpoint of the reflectance scale, providing enough brightness for whole-room application while retaining visible color saturation. The blue reads cleanly without strong green or violet shifts, making it straightforward to coordinate in spaces like bedrooms, bathrooms, or home offices.

It works well alongside Sherwin-Williams Sleepy Blue and Rain for a tonal blue palette, while Accessible Beige adds warmth as an adjacent neutral, and Naval or Iron Ore can serve as deeper anchoring accents.
