San Francisco Bay vs Regale Blue
Where San Francisco Bay belongs to Benjamin Moore's range, Regale Blue is a Sherwin-Williams color. These are both blues, so the question isn't which hue to choose — it's where within blue to land. Regale Blue (LRV 42) reflects noticeably more light than San Francisco Bay (LRV 38), a difference of 4 points that becomes especially apparent in rooms with limited natural light. San Francisco Bay runs blue while Regale Blue is decidedly cool, which means they'll respond very differently to warm vs cool light sources. The ΔE 5.4 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
