Cadet vs Castlegate
Cadet and Castlegate come from the same Sherwin-Williams collection. Hue-wise, Cadet belongs to the blue-grey family and Castlegate to the grey family. The 6-point LRV gap — 37 for Castlegate vs 31 for Cadet — means Castlegate will open up a space more effectively. Both share a neutral character, which means they'll respond to light and surrounding materials in similar ways. ΔE 5.1 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.
Cadet vs Castlegate in Real Spaces
2 real rooms side by side. Cadet and Castlegate 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. Castlegate reads slightly lighter here — a subtle but real difference in how open the space feels.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Castlegate has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

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.
