Pebble grey vs Illusion
Where Pebble grey belongs to RAL Classic's range, Illusion is a Sherwin-Williams color. These are both greige-greys, so the question isn't which hue to choose — it's where within greige-grey to land. Pebble grey (LRV 45) reflects noticeably more light than Illusion (LRV 40), a difference of 5 points that becomes especially apparent in rooms with limited natural light. At ΔE 3.0, 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.

Digital color is approximate.
