Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Endless Sea vs Santorini Blue in Real Spaces
2 real rooms side by side. Endless Sea and Santorini Blue 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
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Santorini Blue has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
House
A full exterior is the most demanding test for a paint color — scale and outdoor light both amplify differences that seem small on a swatch. Santorini Blue has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

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.
