Endless Sea vs Secure Blue

Both from Sherwin-Williams's palette. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. Secure Blue (LRV 22) reflects noticeably more light than Endless Sea (LRV 9), a difference of 14 points that becomes especially apparent in rooms with limited natural light. Both lean cool, so they'll behave similarly in mixed or changing light conditions. With a ΔE of 19.4, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
