Cement grey vs RAL 340-2
Cement grey (RAL Classic) and RAL 340-2 (RAL Effect) come from different manufacturers. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. The 6-point LRV gap — 30 for RAL 340-2 vs 24 for Cement grey — means RAL 340-2 will open up a space more effectively. A ΔE of 17.0 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Cement grey vs RAL 340-2 in Real Spaces
5 real rooms side by side. Seeing Cement grey and RAL 340-2 in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
Living Room
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. RAL 340-2 reads slightly lighter here — a subtle but real difference in how open the space feels.
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 340-2 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 340-2 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 340-2 has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
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 340-2 has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

Cement grey vs RAL 340-2 Simulated Comparison
5 simulated room previews — drag the slider on each to see Cement grey on one side and RAL 340-2 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.
