River Valley vs Ancona Blue
Where River Valley belongs to Dulux's range, Ancona Blue is a Farrow & Ball color. These are both blues, so the question isn't which hue to choose — it's where within blue to land. Ancona Blue (LRV 48) reflects noticeably more light than River Valley (LRV 44), a difference of 4 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 6.9 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
