About Peppercorn
Peppercorn LRV and undertone
Sherwin-Williams Peppercorn (SW 7674) has an LRV of 10, placing it firmly in the dark range. Light Reflectance Value describes the percentage of visible light a color reflects, with lower numbers indicating less reflection. At LRV 10, Peppercorn absorbs much of the light that reaches its surface, so walls can look very deep and may need thoughtful lighting. Its color family is gray, and its calculated undertone is neutral. That means the supplied color data identifies no pronounced warm or cool undertone. Surrounding finishes and the room’s light can still affect how a neutral gray appears in practice.
Peppercorn in other brands
Benjamin Moore Iron Mountain (2134-30) and PPG Knight’s Armor (PPG1001-6) are the nearest listed matches. Both have ΔE values of 1.8, which means they are very close but not necessarily indistinguishable. Iron Mountain has an LRV of 10.96, while Knight’s Armor has an LRV of 11.0, so both reflect slightly more light than Peppercorn. Benjamin Moore Wrought Iron (2124-10) has an LRV of 8.17 and a ΔE of 5.0. It is darker by LRV, but the larger color difference makes it a less exact substitute. Behr Midnight Blue (N480-7), at LRV 9 and ΔE 5.9, is another darker option with a noticeable difference. Compare dried samples directly because similar reflectance does not guarantee an identical gray appearance.
