Understanding a color's undertone is key to avoiding combinations that clash — it often matters more than the surface color itself. Limestone (#6A655C) by Sherwin-Williams is a deep neutral paint color with a understated, nearly neutral quality. It delivers a grounded richness that adds drama and sophistication. 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. At an LRV of 13 it absorbs more light than it reflects, creating a moody, enveloping atmosphere. Deep neutrals like this create contrast and gravitas on accent walls, exterior facades, and kitchen cabinetry, pairing well with lighter trim. Satin or semi-gloss finishes help deep colors reflect just enough light to show their full depth, especially on accent walls and trim. Because Limestone 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. If Sherwin-Williams is unavailable in your area, close cross-brand alternatives exist from Benjamin Moore, Valspar, Kilz and others.
