Light grey vs Monorail Silver
Light grey is a RAL Classic color while Monorail Silver comes from Sherwin-Williams. These are both greys, so the question isn't which hue to choose — it's where within grey to land. At LRV 58 vs 50, Light grey will read as the brighter of the two — a 9-point gap that matters most in north-facing or low-light rooms. At ΔE 4.3, the difference is perceptible but not dramatic — the two can work harmoniously in the same space. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Light grey vs Monorail Silver in Real Spaces
3 real rooms side by side. Light grey and Monorail Silver 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
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. Light grey returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The LRV gap is large enough that Light grey will make the room feel meaningfully brighter than Monorail Silver would.
House
At full exterior scale, the difference between these two colors becomes much easier to judge than from a small chip. The LRV gap is large enough that Light grey will make the room feel meaningfully brighter than Monorail Silver would.

Light grey vs Monorail Silver Simulated Comparison
5 simulated room previews — drag the slider on each to see Light grey on one side and Monorail Silver 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.
