Gustavian Blue vs Celestial in Real Spaces
3 real rooms side by side. Seeing Gustavian Blue and Celestial in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Celestial has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Front Door
On a front door, the color is both the first and last thing you see — a context where even a modest tonal difference reads clearly. Celestial reads slightly lighter here — a subtle but real difference in how open the space feels.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Celestial has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

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