Carbon Copy vs Guilford Green in Real Spaces
3 real rooms side by side. Seeing Carbon Copy and Guilford Green 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. Guilford Green reflects noticeably more light off the walls, making the space read more open than Carbon Copy.
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. Guilford Green returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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. Guilford Green returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Carbon Copy vs Guilford Green Simulated Comparison
5 simulated room previews — drag the slider on each to see Carbon Copy on one side and Guilford Green 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.
