Lullaby vs Mountain Air
Both from Sherwin-Williams's palette. Both sit in the blue-grey family, which is useful context if you're narrowing within a single hue direction. Mountain Air (LRV 73) reflects noticeably more light than Lullaby (LRV 65), a difference of 9 points that becomes especially apparent in rooms with limited natural light. Both lean cool, so they'll behave similarly in mixed or changing light conditions. The ΔE 4.4 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
