Cloud Nine vs Guilford Green
Both from Benjamin Moore's palette. Cloud Nine reads as yellow, while Guilford Green reads as beige-green — two distinct hue families, not close cousins. Cloud Nine (LRV 84) reflects noticeably more light than Guilford Green (LRV 57), a difference of 26 points that becomes especially apparent in rooms with limited natural light. Both lean yellow, so they'll behave similarly in mixed or changing light conditions. With a ΔE of 16.9, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Cloud Nine vs Guilford Green in Real Spaces
3 real rooms side by side. Seeing Cloud Nine 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
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The LRV gap is large enough that Cloud Nine will make the room feel meaningfully brighter than Guilford Green would.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. Cloud Nine reflects noticeably more light off the walls, making the space read more open than Guilford Green.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. Cloud Nine reflects noticeably more light off the walls, making the space read more open than Guilford Green.

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