Calluna vs Treron
Both are Farrow & Ball colors. Calluna reads as grey, while Treron reads as greige-grey — two distinct hue families, not close cousins. At LRV 57 vs 25, Calluna will read as the brighter of the two — a 32-point gap that matters most in north-facing or low-light rooms. The tonal difference — Calluna's neutral character against Treron's warm — becomes most visible against white trim or in morning light. At ΔE 27.8, 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.
Calluna vs Treron in Real Spaces
5 real rooms side by side. Seeing Calluna and Treron 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. Calluna 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 Calluna will make the room feel meaningfully brighter than Treron 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 Calluna will make the room feel meaningfully brighter than Treron would.
House
At full exterior scale, the difference between these two colors becomes much easier to judge than from a small chip. The LRV gap is large enough that Calluna will make the room feel meaningfully brighter than Treron would.

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