Wet Concrete vs RAL 340-2
Where Wet Concrete belongs to Benjamin Moore's range, RAL 340-2 is a RAL Effect color. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. They have nearly identical light reflectance values (27 vs 30), so they'll read as similarly Medium in most lighting conditions. The ΔE 4.2 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

Wet Concrete vs RAL 340-2 Simulated Comparison
5 simulated room previews — drag the slider on each to see Wet Concrete 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.
