Castor vs Ammonite
Castor is a Cloverdale Paint color while Ammonite comes from Farrow & Ball. Castor reads as greige-grey, while Ammonite reads as beige-greige — two distinct hue families, not close cousins. At LRV 69 vs 15, Ammonite will read as the brighter of the two — a 54-point gap that matters most in north-facing or low-light rooms. At ΔE 41.3, 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 vs Ammonite in Real Spaces
5 real rooms side by side. Seeing Castor and Ammonite 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. Ammonite returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. The LRV gap is large enough that Ammonite will make the room feel meaningfully brighter than Castor would.
Kitchen
Kitchen lighting tends to be bright and directional, which sharpens contrast and makes undertone differences more apparent. The LRV gap is large enough that Ammonite will make the room feel meaningfully brighter than Castor would.
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. Ammonite reflects noticeably more light off the walls, making the space read more open than Castor.

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