About Thunder Gray
Thunder Gray (SW 7645) is a very dark warm gray (greige) from Sherwin-Williams with a warm yellow undertone. With an LRV of 9, Thunder Gray absorbs most light. It creates a dramatic, enveloping look and suits accent walls, cabinetry and well-lit rooms.
In north-facing rooms the cool daylight tones down Thunder Gray's warmth, so it can read a little grayer; south- and west-facing light brings the warmth forward. It's a good fit for accent walls, front doors, cabinetry and powder rooms. It's very close to Urbane Bronze (SW 7048); you'd mostly see the difference side by side.
How Thunder Gray changes with the light
Thunder Gray is a deep color. In north-facing or dim rooms it reads darker and cozier; in south-facing rooms it shows more of its color. Either can work, depending on the mood you want.
North-facing rooms
Thunder Gray will read even deeper in north light: great for a cozy, enveloping room, less so if you want it bright.
East-facing rooms
Thunder Gray will look warmer and brighter in the morning and cooler and grayer by afternoon; check a sample at both times.
South-facing rooms
South light keeps Thunder Gray from feeling heavy, so deep colors work well here.
West-facing rooms
Thunder Gray will glow warmer in the late afternoon.
