About Porpoise
Porpoise LRV and undertone
Sherwin-Williams Porpoise (SW 7047) has an LRV of 13, placing it in the dark range. Its color family is brown, and its calculated warm yellow undertone may become more noticeable depending on the light source and surrounding colors. An LRV of 13 means Porpoise reflects relatively little available light, so it can create strong visual depth when used on walls. Dark colors may also make a room feel less bright, particularly where natural light is limited. Consider the size and orientation of the room, as well as the contrast with ceilings, trim, and adjacent surfaces. A test patch can show how the brown family and warm undertone respond throughout the day.
Porpoise in other brands
Benjamin Moore Kendall Charcoal (HC-166) is the closest listed alternative across brands, with an LRV of 14.61 and ΔE 3.8. This represents a close but visible difference when the paints are compared side by side. PPG Knight’s Armor (PPG1001-6), with LRV 11 and ΔE 6.6, is only similar. Benjamin Moore Iron Mountain (2134-30) has an LRV of 10.96 and ΔE 7.0, also indicating similarity rather than a close match. Valspar Almost Charcoal (4008-2B), at LRV 15.93 and ΔE 8.5, has a larger measured difference. These alternatives should not be treated as exact replacements based on their names or darkness alone. ΔE measures color difference, while LRV measures light reflectance; the two values describe different properties.
Lighter and darker Sherwin-Williams alternatives

Sherwin-Williams Grizzle Gray (SW 7068) shares Porpoise’s LRV of 13, but its ΔE of 5.4 indicates only a similar measured color. Sherwin-Williams Pewter Green (SW 6208), with LRV 12, is slightly darker by reflectance and has ΔE 6.6. Sherwin-Williams Peppercorn (SW 7674) has an LRV of 10, making it darker, with ΔE 7.3.
