Biscay Bay vs Aquarium
Where Biscay Bay belongs to PPG's range, Aquarium is a Sherwin-Williams color. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. Biscay Bay (LRV 38) reflects noticeably more light than Aquarium (LRV 32), a difference of 6 points that becomes especially apparent in rooms with limited natural light. The ΔE 4.8 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
