Greyhound vs RAL 840-3
Greyhound is a PPG color while RAL 840-3 comes from RAL Effect. Both sit in the greige-grey family, which is useful context if you're narrowing within a single hue direction. At LRV 46 vs 41, RAL 840-3 will read as the brighter of the two — a 5-point gap that matters most in north-facing or low-light rooms. At ΔE 3.0, the difference is perceptible but not dramatic — the two can work harmoniously in the same space. Below you'll find 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Greyhound vs RAL 840-3 in Real Spaces
5 real rooms side by side. Greyhound and RAL 840-3 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. RAL 840-3 has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Kitchen
Kitchen lighting tends to be bright and directional, which sharpens contrast and makes undertone differences more apparent. The brightness difference is modest but present — RAL 840-3 gives the walls a little more lift.
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 — RAL 840-3 gives the walls a little more lift.
House
At full exterior scale, the difference between these two colors becomes much easier to judge than from a small chip. The brightness difference is modest but present — RAL 840-3 gives the walls a little more lift.

Greyhound vs RAL 840-3 Simulated Comparison
5 simulated room previews — drag the slider on each to see Greyhound on one side and RAL 840-3 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.
