Lamp Room Gray vs S 3005-G20Y
Lamp Room Gray (Farrow & Ball) and S 3005-G20Y (NCS) come from different manufacturers. These are both greys, so the question isn't which hue to choose — it's where within grey to land. The 3-point LRV gap — 44 for Lamp Room Gray vs 40 for S 3005-G20Y — means Lamp Room Gray will open up a space more effectively. Both share a neutral character, which means they'll respond to light and surrounding materials in similar ways. ΔE 3.3 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Lamp Room Gray vs S 3005-G20Y in Real Spaces
2 real rooms side by side. Lamp Room Gray and S 3005-G20Y 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
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. Lamp Room Gray reads slightly lighter here — a subtle but real difference in how open the space feels.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Lamp Room Gray has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

5 simulated room previews — drag the slider on each to see Lamp Room Gray on one side and S 3005-G20Y 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.
