Narrow Lane vs Warm Truffle

Both from Dulux's palette. These are both greige-greys, so the question isn't which hue to choose — it's where within greige-grey to land. Warm Truffle (LRV 46) reflects noticeably more light than Narrow Lane (LRV 41), a difference of 5 points that becomes especially apparent in rooms with limited natural light. Both lean warm, so they'll behave similarly in mixed or changing light conditions. The ΔE 3.9 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
