Grey aluminium vs Renwick Heather
Grey aluminium (RAL Classic) and Renwick Heather (Sherwin-Williams) 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 7-point LRV gap — 29 for Grey aluminium vs 22 for Renwick Heather — means Grey aluminium will open up a space more effectively. ΔE 5.8 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.
