Sherwin Williams

Thunder Gray

SW 7645

Thunder Gray (SW, hex #57534C) is a dark neutral with green and blue-gray undertones and an LRV of 9, resulting in very low light reflectance and a deep, saturated appearance. The green-gray blend distinguishes it from standard charcoals and gives it a cooler, more complex character. Within the Sherwin-Williams line, it pairs with Pure White, Eider White, Urbane Bronze, and Rookwood Red.

Pure White and Eider White provide high-contrast trim options that define architectural details against this dark base. Urbane Bronze offers a closely related dark neutral, while Rookwood Red introduces a warm contrasting accent.
