Grey Blue vs RAL 120-M
Grey Blue (RAL Classic) and RAL 120-M (RAL Effect) come from different manufacturers. Hue-wise, Grey Blue belongs to the blue-grey family and RAL 120-M to the grey family. The 19-point LRV gap — 27 for RAL 120-M vs 7 for Grey Blue — means RAL 120-M will open up a space more effectively. A ΔE of 28.4 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Grey Blue vs RAL 120-M in Real Spaces
3 real rooms side by side. Seeing Grey Blue and RAL 120-M in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
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. RAL 120-M returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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 120-M returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. RAL 120-M returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Grey Blue vs RAL 120-M Simulated Comparison
5 simulated room previews — drag the slider on each to see Grey Blue on one side and RAL 120-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.
