Black grey vs Light grey
Both from RAL Classic's palette. Black grey reads as blue-grey, while Light grey reads as grey — two distinct hue families, not close cousins. Light grey (LRV 58) reflects noticeably more light than Black grey (LRV 6), a difference of 52 points that becomes especially apparent in rooms with limited natural light. With a ΔE of 59.5, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Black grey vs Light grey in Real Spaces
3 real rooms side by side. Seeing Black grey and Light grey in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
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 LRV gap is large enough that Light grey will make the room feel meaningfully brighter than Black grey would.
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. Light grey reflects noticeably more light off the walls, making the space read more open than Black grey.
Front Door
A front door is a focal point — small color differences read clearly at this concentrated scale. The LRV gap is large enough that Light grey will make the room feel meaningfully brighter than Black grey would.

Black grey vs Light grey Simulated Comparison
5 simulated room previews — drag the slider on each to see Black grey 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.
