Let it Rain vs Morning Fog
Both from Sherwin-Williams's palette. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. Morning Fog (LRV 42) reflects noticeably more light than Let it Rain (LRV 34), a difference of 7 points that becomes especially apparent in rooms with limited natural light. Both lean neutral, so they'll behave similarly in mixed or changing light conditions. The ΔE 6.0 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Let it Rain vs Morning Fog in Real Spaces

Digital color is approximate.
