Rock Gray vs Shark Gray
Both are Benjamin Moore colors. These are both greys, so the question isn't which hue to choose — it's where within grey to land. With LRVs of 24 and 23, they'll behave almost identically in terms of how much light they reflect back into a room. They share a blue quality — useful to know if you're layering them in the same space. With a ΔE of 1.2, the difference is subtle — you'd need them side by side to reliably tell them apart.

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.
