Aquitaine vs Tranquil Aqua
Both are Sherwin-Williams colors. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. At LRV 38 vs 30, Aquitaine will read as the brighter of the two — a 8-point gap that matters most in north-facing or low-light rooms. They share a cool quality — useful to know if you're layering them in the same space. At ΔE 6.5, the difference is perceptible but not dramatic — the two can work harmoniously in the same space. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Aquitaine vs Tranquil Aqua in Real Spaces
2 real rooms side by side. Aquitaine 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.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The brightness difference is modest but present — Aquitaine gives the walls a little more lift.
House
At full exterior scale, the difference between these two colors becomes much easier to judge than from a small chip. The brightness difference is modest but present — Aquitaine gives the walls a little more lift.

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.
