Naples Blue vs RAL 680-3
Where Naples Blue belongs to Benjamin Moore's range, RAL 680-3 is a RAL Effect color. These are both blues, so the question isn't which hue to choose — it's where within blue to land. Naples Blue (LRV 15) reflects noticeably more light than RAL 680-3 (LRV 10), a difference of 4 points that becomes especially apparent in rooms with limited natural light. The ΔE 3.4 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Naples Blue vs RAL 680-3 in Real Spaces
2 real rooms side by side. Naples Blue and RAL 680-3 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
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. Naples Blue reads slightly lighter here — a subtle but real difference in how open the space feels.
Bathroom

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.
