Mortar vs Simply Sage

Both from Behr's palette. These are both greys, so the question isn't which hue to choose — it's where within grey to land. Mortar (LRV 67) reflects noticeably more light than Simply Sage (LRV 38), a difference of 29 points that becomes especially apparent in rooms with limited natural light. Both lean yellow, so they'll behave similarly in mixed or changing light conditions. With a ΔE of 18.2, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
