Galaxy vs Cement grey
Where Galaxy belongs to Benjamin Moore's range, Cement grey is a RAL Classic color. These are both greys, so the question isn't which hue to choose — it's where within grey to land. Cement grey (LRV 24) reflects noticeably more light than Galaxy (LRV 6), a difference of 18 points that becomes especially apparent in rooms with limited natural light. With a ΔE of 30.3, 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 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
