Sapphire blue vs Cement grey
Sapphire blue and Cement grey come from the same RAL Classic collection. The 18-point LRV gap — 24 for Cement grey vs 6 for Sapphire blue — means Cement grey will open up a space more effectively. A ΔE of 41.6 puts these firmly in different territory — two distinct design choices rather than close alternatives.
Sapphire blue vs Cement grey Color Comparison
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.

Sapphire blue vs Cement grey in Real Spaces
Seeing Sapphire 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. Showing 6 room types where both colors have photos.
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. Cement grey reflects noticeably more light off the walls, making the space read more open than Sapphire blue.

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. Cement grey 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. Cement grey 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. Cement grey 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. Cement grey reflects noticeably more light off the walls, making the space read more open than Sapphire blue.

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. Cement grey returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
