Acier vs Bedrock
Both from Sherwin-Williams's palette. These are both greys, so the question isn't which hue to choose — it's where within grey to land. They have nearly identical light reflectance values (32 vs 34), so they'll read as similarly Medium in most lighting conditions. Both lean neutral, so they'll behave similarly in mixed or changing light conditions. The ΔE 3.0 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.

Acier vs Bedrock Simulated Comparison
5 simulated room previews — drag the slider on each to see Acier on one side and Bedrock 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.
