Castor Grey vs Green Smoke
Castor Grey is a Cloverdale Paint color while Green Smoke comes from Farrow & Ball. Both sit in the green-grey family, which is useful context if you're narrowing within a single hue direction. With LRVs of 19 and 19, they'll behave almost identically in terms of how much light they reflect back into a room. At ΔE 3.1, the difference is perceptible but not dramatic — the two can work harmoniously in the same space. Below you'll find 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Castor Grey vs Green Smoke in Real Spaces
5 real rooms side by side. Castor Grey and Green Smoke 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
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. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.
Kitchen
Kitchen lighting tends to be bright and directional, which sharpens contrast and makes undertone differences more apparent. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.
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. The distinction reads clearly at room scale, making the choice between them concrete.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.

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