Astronomical vs Cannon Ball
Astronomical (Behr) and Cannon Ball (Dulux) come from different manufacturers. These are both greys, so the question isn't which hue to choose — it's where within grey to land. The 4-point LRV gap — 11 for Cannon Ball vs 7 for Astronomical — means Cannon Ball will open up a space more effectively. Where Astronomical leans green, Cannon Ball reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 3.8 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Astronomical vs Cannon Ball in Real Spaces
2 real rooms side by side. Astronomical and Cannon Ball 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.
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. Cannon Ball has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Cannon Ball has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

Astronomical vs Cannon Ball Simulated Comparison
5 simulated room previews — drag the slider on each to see Astronomical on one side and Cannon Ball 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.
