London Fog vs Thunder
Both from Benjamin Moore's palette. These are both greige-greys, so the question isn't which hue to choose — it's where within greige-grey to land. London Fog (LRV 56) reflects noticeably more light than Thunder (LRV 48), a difference of 9 points that becomes especially apparent in rooms with limited natural light. Both lean red, so they'll behave similarly in mixed or changing light conditions. The ΔE 5.5 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
