Cool Sky vs Blueberry White
Cool Sky (Cloverdale Paint) and Blueberry White (Dulux) come from different manufacturers. Hue-wise, Cool Sky belongs to the blue family and Blueberry White to the blue-white family. Their light reflectance values are nearly the same — 77 vs 75 — so neither will read significantly brighter or darker than the other. A ΔE of 2.1 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Cool Sky vs Blueberry White in Real Spaces
2 real rooms side by side. Cool Sky and Blueberry White 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.
Living Room
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.

Cool Sky vs Blueberry White Simulated Comparison
5 simulated room previews — drag the slider on each to see Cool Sky on one side and Blueberry White on the other.
Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
