Undine vs Holiday Turquoise
Where Undine belongs to Behr's range, Holiday Turquoise is a Sherwin-Williams color. These are both blues, so the question isn't which hue to choose — it's where within blue to land. Holiday Turquoise (LRV 49) reflects noticeably more light than Undine (LRV 43), a difference of 6 points that becomes especially apparent in rooms with limited natural light. Undine runs green and blue while Holiday Turquoise is decidedly cool, which means they'll respond very differently to warm vs cool light sources. At ΔE 2.3, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room.
