Celestial Cloud 2 vs River Valley
Both from Dulux's palette. These are both blues, so the question isn't which hue to choose — it's where within blue to land. River Valley (LRV 44) reflects noticeably more light than Celestial Cloud 2 (LRV 32), a difference of 12 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 9.0 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
