Blue Iris vs Modern Lavender

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. Blue Iris (LRV 73) reflects noticeably more light than Modern Lavender (LRV 40), a difference of 33 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. With a ΔE of 19.1, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
