Ironclad vs Nocturne

Both from Sherwin-Williams's palette. Ironclad reads as grey, while Nocturne reads as greige-grey — two distinct hue families, not close cousins. Ironclad (LRV 11) reflects noticeably more light than Nocturne (LRV 8), a difference of 3 points that becomes especially apparent in rooms with limited natural light. Ironclad runs neutral while Nocturne is decidedly warm, which means they'll respond very differently to warm vs cool light sources. The ΔE 6.8 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
