Jamestown Blue vs Celestial Cloud 2
Jamestown Blue is a Benjamin Moore color while Celestial Cloud 2 comes from Dulux. These are both blues, so the question isn't which hue to choose — it's where within blue to land. With LRVs of 34 and 32, they'll behave almost identically in terms of how much light they reflect back into a room. The tonal difference — Jamestown Blue's blue character against Celestial Cloud 2's cool — becomes most visible against white trim or in morning light. With a ΔE of 1.6, the difference is subtle — you'd need them side by side to reliably tell them apart. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Jamestown Blue vs Celestial Cloud 2 in Real Spaces
2 real rooms side by side. Jamestown Blue and Celestial Cloud 2 are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Dining Room
Dining room light is typically the warmest in the house, which shifts both colors toward the red end of the spectrum compared to daylight. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.
Front Door
Front doors are seen in isolation against the rest of the facade, which makes them a high-stakes surface where even subtle differences matter. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.
