Apollo Blue vs Knoxville Gray
Apollo Blue and Knoxville Gray come from the same Benjamin Moore collection. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. The 8-point LRV gap — 24 for Apollo Blue vs 16 for Knoxville Gray — means Apollo Blue will open up a space more effectively. Both share a blue character, which means they'll respond to light and surrounding materials in similar ways. ΔE 9.5 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

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.
