Window grey vs Interesting Aqua in Real Spaces

2 real rooms side by side. Window grey and Interesting 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.

Before committing to either color, test physical samples in your own space under the light you actually live with.
