El Capitan vs Resonant Blue
Where El Capitan belongs to Behr's range, Resonant Blue is a Sherwin-Williams color. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. Resonant Blue (LRV 30) reflects noticeably more light than El Capitan (LRV 25), a difference of 5 points that becomes especially apparent in rooms with limited natural light. El Capitan runs blue while Resonant Blue is decidedly cool, which means they'll respond very differently to warm vs cool light sources. The ΔE 9.3 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
