Castor Grey vs Pewter Green
Castor Grey is a Cloverdale Paint color while Pewter Green comes from Sherwin-Williams. These are both green-greys, so the question isn't which hue to choose — it's where within green-grey to land. At LRV 19 vs 12, Castor Grey will read as the brighter of the two — a 7-point gap that matters most in north-facing or low-light rooms. At ΔE 10.7, these are genuinely distinct colors — a strong contrast if used together, or a meaningful choice between two different directions. Below you'll find 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Castor Grey vs Pewter Green in Real Spaces
5 real rooms side by side. Seeing Castor Grey and Pewter Green in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
Living Room
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. Castor Grey has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. The brightness difference is modest but present — Castor Grey gives the walls a little more lift.
Kitchen
Kitchen lighting tends to be bright and directional, which sharpens contrast and makes undertone differences more apparent. The brightness difference is modest but present — Castor Grey gives the walls a little more lift.
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. Castor Grey reads slightly lighter here — a subtle but real difference in how open the space feels.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The brightness difference is modest but present — Castor Grey gives the walls a little more lift.

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.
