RAL 740-5 vs Naval in Real Spaces
3 real rooms side by side. Seeing RAL 740-5 and Naval in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
Living Room
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. RAL 740-5 reads slightly lighter here — a subtle but real difference in how open the space feels.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. RAL 740-5 has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
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. RAL 740-5 has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

RAL 740-5 vs Naval Simulated Comparison
5 simulated room previews — drag the slider on each to see RAL 740-5 on one side and Naval 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.
