Acier vs Limestone
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. Acier (LRV 32) reflects noticeably more light than Limestone (LRV 13), a difference of 19 points that becomes especially apparent in rooms with limited natural light. Both lean neutral, so they'll behave similarly in mixed or changing light conditions. With a ΔE of 20.5, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.

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.
