Blue Square vs Ammonite
Blue Square is a Behr color while Ammonite comes from Farrow & Ball. Blue Square reads as blue, while Ammonite reads as beige-greige — two distinct hue families, not close cousins. At LRV 69 vs 20, Ammonite will read as the brighter of the two — a 49-point gap that matters most in north-facing or low-light rooms. The tonal difference — Blue Square's blue character against Ammonite's warm — becomes most visible against white trim or in morning light. At ΔE 40.4, 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.
Blue Square vs Ammonite in Real Spaces
5 real rooms side by side. Seeing Blue Square 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 Blue Square 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 Blue Square would.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The LRV gap is large enough that Ammonite will make the room feel meaningfully brighter than Blue Square would.
Kitchen Cabinets
On cabinetry, undertone and temperature become more pronounced against countertops and hardware. The LRV gap is large enough that Ammonite will make the room feel meaningfully brighter than Blue Square would.

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.
