Lamp Black vs RAL 770-M
Lamp Black (Little Greene) and RAL 770-M (RAL Effect) come from different manufacturers. Hue-wise, Lamp Black belongs to the grey family and RAL 770-M to the beige-greige family. The 21-point LRV gap — 24 for RAL 770-M vs 3 for Lamp Black — means RAL 770-M will open up a space more effectively. A ΔE of 43.2 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Lamp Black vs RAL 770-M in Real Spaces
5 real rooms side by side. Seeing Lamp Black and RAL 770-M 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
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. RAL 770-M reflects noticeably more light off the walls, making the space read more open than Lamp Black.
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. RAL 770-M returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. RAL 770-M returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. RAL 770-M returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. RAL 770-M returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Lamp Black vs RAL 770-M Simulated Comparison
5 simulated room previews — drag the slider on each to see Lamp Black on one side and RAL 770-M 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.
