S 4500-N vs RAL 830-M
S 4500-N (NCS) and RAL 830-M (RAL Effect) come from different manufacturers. These are both greys, so the question isn't which hue to choose — it's where within grey to land. The 5-point LRV gap — 27 for S 4500-N vs 22 for RAL 830-M — means S 4500-N will open up a space more effectively. ΔE 5.0 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
S 4500-N vs RAL 830-M in Real Spaces
2 real rooms side by side. S 4500-N and RAL 830-M 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.
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. S 4500-N 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. S 4500-N has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

S 4500-N vs RAL 830-M Simulated Comparison
5 simulated room previews — drag the slider on each to see S 4500-N on one side and RAL 830-M 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.
