Castor vs Granite
Castor is a Cloverdale Paint color while Granite comes from PPG. These are both greige-greys, so the question isn't which hue to choose — it's where within greige-grey to land. With LRVs of 15 and 14, they'll behave almost identically in terms of how much light they reflect back into a room. With a ΔE of 0.4, the difference is subtle — you'd need them side by side to reliably tell them apart. Below you'll find 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Castor vs Granite in Real Spaces
5 real rooms side by side. Castor and Granite 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. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.
Kitchen
Kitchen lighting tends to be bright and directional, which sharpens contrast and makes undertone differences more apparent. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.
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. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.

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