Through the Looking Glass vs RAL 830-1
Where Through the Looking Glass belongs to Benjamin Moore's range, RAL 830-1 is a RAL Effect color. These are both greys, so the question isn't which hue to choose — it's where within grey to land. They have nearly identical light reflectance values (51 vs 50), so they'll read as similarly Medium in most lighting conditions. At ΔE 2.5, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.
