River Silt vs RAL 770-4
Where River Silt belongs to Benjamin Moore's range, RAL 770-4 is a RAL Effect color. Both sit in the greige-grey family, which is useful context if you're narrowing within a single hue direction. They have nearly identical light reflectance values (21 vs 20), so they'll read as similarly Dark in most lighting conditions. The ΔE 3.5 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.

River Silt vs RAL 770-4 Simulated Comparison
5 simulated room previews — drag the slider on each to see River Silt on one side and RAL 770-4 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.
