Nautical Star vs RAL 820-2
Nautical Star (PPG) and RAL 820-2 (RAL Effect) come from different manufacturers. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. The 4-point LRV gap — 46 for Nautical Star vs 42 for RAL 820-2 — means Nautical Star will open up a space more effectively. ΔE 3.2 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Nautical Star vs RAL 820-2 in Real Spaces
4 real rooms side by side. Nautical Star and RAL 820-2 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. Nautical Star has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Nautical Star has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
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. Nautical Star 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. Nautical Star has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

Nautical Star vs RAL 820-2 Simulated Comparison
5 simulated room previews — drag the slider on each to see Nautical Star on one side and RAL 820-2 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.
