Industrial Blue vs Grey Blue in Real Spaces
1 real room side by side. Industrial Blue and Grey 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. Industrial Blue has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

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