Indigo vs Sea Isle

Both from Benjamin Moore's palette. These are both blues, so the question isn't which hue to choose — it's where within blue to land. Sea Isle (LRV 62) reflects noticeably more light than Indigo (LRV 57), a difference of 5 points that becomes especially apparent in rooms with limited natural light. Both lean blue, so they'll behave similarly in mixed or changing light conditions. The ΔE 3.3 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
