Castleton Mist vs Mellowed Ivory

Both from Benjamin Moore's palette. These are both beige-yellows, so the question isn't which hue to choose — it's where within beige-yellow to land. Mellowed Ivory (LRV 64) reflects noticeably more light than Castleton Mist (LRV 61), a difference of 3 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. The ΔE 5.9 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
