RAL 660-2 vs Naval
RAL 660-2 is a RAL Effect color while Naval comes from Sherwin-Williams. These are both blues, so the question isn't which hue to choose — it's where within blue to land. At LRV 14 vs 4, RAL 660-2 will read as the brighter of the two — a 10-point gap that matters most in north-facing or low-light rooms. At ΔE 37.1, these are genuinely distinct colors — a strong contrast if used together, or a meaningful choice between two different directions. Below you'll find 6 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
RAL 660-2 vs Naval in Real Spaces
6 real rooms side by side. Seeing RAL 660-2 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
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. RAL 660-2 returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. The LRV gap is large enough that RAL 660-2 will make the room feel meaningfully brighter than Naval would.
Kitchen
Kitchen lighting tends to be bright and directional, which sharpens contrast and makes undertone differences more apparent. The LRV gap is large enough that RAL 660-2 will make the room feel meaningfully brighter than Naval would.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The LRV gap is large enough that RAL 660-2 will make the room feel meaningfully brighter than Naval would.
House
At full exterior scale, the difference between these two colors becomes much easier to judge than from a small chip. The LRV gap is large enough that RAL 660-2 will make the room feel meaningfully brighter than Naval would.

RAL 660-2 vs Naval Simulated Comparison
5 simulated room previews — drag the slider on each to see RAL 660-2 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.
