Aqua-Sphere vs Tranquil Aqua
Both from Sherwin-Williams's palette. Aqua-Sphere reads as blue-grey, while Tranquil Aqua reads as blue — two distinct hue families, not close cousins. Aqua-Sphere (LRV 41) reflects noticeably more light than Tranquil Aqua (LRV 30), a difference of 11 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. The ΔE 9.6 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Aqua-Sphere vs Tranquil Aqua in Real Spaces
2 real rooms side by side. Aqua-Sphere and Tranquil Aqua are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Living Room
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The LRV gap is large enough that Aqua-Sphere will make the room feel meaningfully brighter than Tranquil Aqua would.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. Aqua-Sphere reflects noticeably more light off the walls, making the space read more open than Tranquil Aqua.

Aqua-Sphere vs Tranquil Aqua Simulated Comparison
5 simulated room previews — drag the slider on each to see Aqua-Sphere on one side and Tranquil Aqua on the other.
Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
