White aluminium (LRV 46) reflects noticeably more light than Gray Matters (LRV 39), a difference of 7 points that becomes especially apparent in rooms with limited natural light. The ΔE 3.7 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
White aluminium vs Gray Matters in Real Spaces
3 real rooms side by side. White aluminium and Gray Matters are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Living Room
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The brightness difference is modest but present — White aluminium gives the walls a little more lift.
Kitchen
In a kitchen, colors are seen under bright task lighting that amplifies undertones — what reads neutral elsewhere can show its hand here. White aluminium reads slightly lighter here — a subtle but real difference in how open the space feels.
House
Seen across an entire facade, subtle tonal differences become pronounced. What reads as nearly the same on a chip often reads as clearly different at scale. White aluminium reads slightly lighter here — a subtle but real difference in how open the space feels.

White aluminium vs Gray Matters Simulated Comparison
5 simulated room previews — drag the slider on each to see White aluminium on one side and Gray Matters 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.
