Limestone vs White Down

Both from Benjamin Moore's palette. Hue-wise, Limestone belongs to the beige-yellow family and White Down to the beige-white family. White Down (LRV 77) reflects noticeably more light than Limestone (LRV 66), a difference of 11 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 7.6 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
