Green Blue vs Cement grey
Green Blue (Farrow & Ball) and Cement grey (RAL Classic) come from different manufacturers. Hue-wise, Green Blue belongs to the blue-green family and Cement grey to the grey family. The 23-point LRV gap — 47 for Green Blue vs 24 for Cement grey — means Green Blue will open up a space more effectively. A ΔE of 22.0 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 6 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Green Blue vs Cement grey in Real Spaces
6 real rooms side by side. Seeing Green Blue and Cement grey 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. Green Blue reflects noticeably more light off the walls, making the space read more open than Cement grey.
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. Green Blue 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. Green Blue 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. Green Blue returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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. Green Blue reflects noticeably more light off the walls, making the space read more open than Cement grey.
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. Green Blue returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Green Blue vs Cement grey Simulated Comparison
5 simulated room previews — drag the slider on each to see Green Blue on one side and Cement grey 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.
