Rhythmic Blue vs Vast Sky
Both from Sherwin-Williams's palette. These are both blues, so the question isn't which hue to choose — it's where within blue to land. Rhythmic Blue (LRV 69) reflects noticeably more light than Vast Sky (LRV 55), a difference of 14 points that becomes especially apparent in rooms with limited natural light. Both lean cool, so they'll behave similarly in mixed or changing light conditions. The ΔE 9.6 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
