Mirror Mirror vs RAL 820-2 in Real Spaces
4 real rooms side by side. Mirror Mirror 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. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.
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. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.
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. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.

5 simulated room previews — drag the slider on each to see Mirror Mirror 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.
