Gossamer Blue vs Light grey
Gossamer Blue is a Benjamin Moore color while Light grey comes from RAL Classic. Gossamer Blue reads as blue, while Light grey reads as grey — two distinct hue families, not close cousins. At LRV 58 vs 55, Light grey will read as the brighter of the two — a 3-point gap that matters most in north-facing or low-light rooms. At ΔE 7.0, 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.
Gossamer Blue vs Light grey in Real Spaces
3 real rooms side by side. Gossamer Blue and Light grey 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 has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The brightness difference is modest but present — Light grey gives the walls a little more lift.
Front Door
Front doors are seen in isolation against the rest of the facade, which makes them a high-stakes surface where even subtle differences matter. Light grey has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

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