Thunder Gray (#57534C) by Sherwin-Williams is a medium gray paint color with a understated, nearly neutral quality. It delivers a versatile mid-tone depth that anchors a room without overwhelming it. On the temperature spectrum this shade leans toward warmth, adding coziness and inviting energy. Its RGB channels are closely balanced, contributing to its neutral, even-keeled visual character. A Light Reflectance Value of 33 gives it moderate light reflection, striking a balance between brightness and depth. A mid-tone neutral at this depth adds sophisticated warmth or coolness to living rooms, bedrooms, and transitional hallways, grounding the space without closing it in. A satin or eggshell finish brings out the richness at this depth, and the slight sheen makes walls easier to maintain. Because Thunder Gray carries warm undertones, it pairs naturally with other warm neutrals, creamy whites, and earthy accents like terracotta or caramel. Its warm (golden) undertone means trim and ceiling whites should lean neutral to avoid a jarring clash.
