Celestial vs Cosmos
Both are Sherwin-Williams colors. These are both blues, so the question isn't which hue to choose — it's where within blue to land. At LRV 44 vs 38, Celestial will read as the brighter of the two — a 6-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 4.3, 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.
Celestial vs Cosmos in Real Spaces
2 real rooms side by side. Celestial and Cosmos 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.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. The brightness difference is modest but present — Celestial gives the walls a little more lift.
Front Door
Front doors are seen in isolation against the rest of the facade, which makes them a high-stakes surface where even subtle differences matter. Celestial has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

Celestial vs Cosmos Simulated Comparison
5 simulated room previews — drag the slider on each to see Celestial on one side and Cosmos 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.
