S 4500-N vs Platinum grey
S 4500-N (NCS) and Platinum grey (RAL Classic) 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 — 32 for Platinum grey vs 27 for S 4500-N — means Platinum grey will open up a space more effectively. A ΔE of 2.5 puts them in subtle territory — distinguishable in direct comparison, less so from across a 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 Platinum grey in Real Spaces
2 real rooms side by side. S 4500-N and Platinum grey 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.
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. Platinum grey has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Front Door
On a front door, the color is both the first and last thing you see — a context where even a modest tonal difference reads clearly. Platinum grey reads slightly lighter here — a subtle but real difference in how open the space feels.

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