Calke Green vs Treron
Calke Green and Treron come from the same Farrow & Ball collection. Calke Green reads as green-grey, while Treron reads as greige-grey — two distinct hue families, not close cousins. The 4-point LRV gap — 25 for Treron vs 21 for Calke Green — means Treron will open up a space more effectively. Where Calke Green leans neutral, Treron reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 10.1 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 7 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Calke Green vs Treron in Real Spaces
7 real rooms side by side. Seeing Calke Green 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
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. Treron reads slightly lighter here — a subtle but real difference in how open the space feels.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Treron has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Dining Room
Dining rooms often rely on warm incandescent or candlelight, which flatters warm undertones and mutes cool ones. The brightness difference is modest but present — Treron gives the walls a little more lift.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. Treron has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
House
A full exterior is the most demanding test for a paint color — scale and outdoor light both amplify differences that seem small on a swatch. Treron has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Front Door
On a front door, the color is both the first and last thing you see — a context where even a modest tonal difference reads clearly. Treron reads slightly lighter here — a subtle but real difference in how open the space feels.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Treron has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

Calke Green vs Treron Simulated Comparison
5 simulated room previews — drag the slider on each to see Calke Green 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.
