Slate Pebble vs Ganymede
Slate Pebble (PPG) and Ganymede (Valspar) come from different manufacturers. These are both greys, so the question isn't which hue to choose — it's where within grey to land. The 3-point LRV gap — 46 for Ganymede vs 43 for Slate Pebble — means Ganymede will open up a space more effectively. ΔE 3.5 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.
