The 12-point LRV gap — 69 for Ammonite vs 57 for Guilford Green — means Ammonite will open up a space more effectively. Where Guilford Green leans yellow, Ammonite reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 12.9 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Guilford Green vs Ammonite in Real Spaces
5 real rooms side by side. Seeing Guilford Green 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
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. Ammonite reflects noticeably more light off the walls, making the space read more open than Guilford Green.
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. Ammonite returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Ammonite returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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. Ammonite returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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. Ammonite returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

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