Hostaleaf vs Mountain Pine

Both from Behr's palette. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. Mountain Pine (LRV 15) reflects noticeably more light than Hostaleaf (LRV 9), a difference of 5 points that becomes especially apparent in rooms with limited natural light. Both lean green and blue, so they'll behave similarly in mixed or changing light conditions. The ΔE 9.2 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
