Stamped Concrete vs Thunderous

Both from Sherwin-Williams's palette. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. Stamped Concrete (LRV 35) reflects noticeably more light than Thunderous (LRV 15), a difference of 20 points that becomes especially apparent in rooms with limited natural light. Both lean neutral, so they'll behave similarly in mixed or changing light conditions. With a ΔE of 20.4, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
