River Blue vs Lamp Black
Where River Blue belongs to Benjamin Moore's range, Lamp Black is a Little Greene color. River Blue reads as blue, while Lamp Black reads as grey — two distinct hue families, not close cousins. River Blue (LRV 7) reflects noticeably more light than Lamp Black (LRV 3), a difference of 5 points that becomes especially apparent in rooms with limited natural light. River Blue runs blue while Lamp Black is decidedly purple, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 17.3, 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 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
River Blue vs Lamp Black in Real Spaces
4 real rooms side by side. Seeing River Blue and Lamp Black 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 brightness difference is modest but present — River Blue gives the walls a little more lift.
Kitchen
In a kitchen, colors are seen under bright task lighting that amplifies undertones — what reads neutral elsewhere can show its hand here. River Blue reads slightly lighter here — a subtle but real difference in how open the space feels.
Dining Room
A dining room lit by a dimmed pendant or candles is one of the most forgiving environments for paint — warm light softens almost everything. River Blue has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. River Blue reads slightly lighter here — a subtle but real difference in how open the space feels.

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.
