Secret vs Grey aluminium
Where Secret belongs to Benjamin Moore's range, Grey aluminium is a RAL Classic color. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. Grey aluminium (LRV 29) reflects noticeably more light than Secret (LRV 26), a difference of 3 points that becomes especially apparent in rooms with limited natural light. At ΔE 1.9, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

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.
