RAL 540-1 vs RAL 550-2
RAL 540-1 and RAL 550-2 come from the same RAL Effect collection. RAL 540-1 reads as pink-purple, while RAL 550-2 reads as pink — two distinct hue families, not close cousins. The 4-point LRV gap — 58 for RAL 540-1 vs 54 for RAL 550-2 — means RAL 540-1 will open up a space more effectively. ΔE 4.8 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
RAL 540-1 vs RAL 550-2 in Real Spaces
3 real rooms side by side. RAL 540-1 and RAL 550-2 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.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. RAL 540-1 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. RAL 540-1 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. RAL 540-1 has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

RAL 540-1 vs RAL 550-2 Simulated Comparison
5 simulated room previews — drag the slider on each to see RAL 540-1 on one side and RAL 550-2 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.
