Coastal Grey vs Hazy
Coastal Grey (Dulux) and Hazy (Farrow & Ball) come from different manufacturers. Coastal Grey reads as blue-grey, while Hazy reads as blue — two distinct hue families, not close cousins. The 5-point LRV gap — 56 for Coastal Grey vs 51 for Hazy — means Coastal Grey will open up a space more effectively. Both share a cool character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 2.7 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Coastal Grey vs Hazy in Real Spaces
1 real room side by side. Coastal Grey and Hazy 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.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. Coastal Grey has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

Coastal Grey vs Hazy Simulated Comparison
5 simulated room previews — drag the slider on each to see Coastal Grey on one side and Hazy 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.
