Stargazer vs Cement grey
Stargazer (PPG) and Cement grey (RAL Classic) come from different manufacturers. These are both greys, so the question isn't which hue to choose — it's where within grey to land. The 22-point LRV gap — 46 for Stargazer vs 24 for Cement grey — means Stargazer will open up a space more effectively. A ΔE of 21.3 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.
Stargazer vs Cement grey in Real Spaces
5 real rooms side by side. Seeing Stargazer 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. Stargazer 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. Stargazer 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. Stargazer 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. Stargazer 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. Stargazer reflects noticeably more light off the walls, making the space read more open than Cement grey.

Stargazer vs Cement grey Simulated Comparison
5 simulated room previews — drag the slider on each to see Stargazer 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.
