Cinnamon Slate vs Onyx
Both from Benjamin Moore's palette. These are both greys, so the question isn't which hue to choose — it's where within grey to land. Cinnamon Slate (LRV 20) reflects noticeably more light than Onyx (LRV 5), a difference of 15 points that becomes especially apparent in rooms with limited natural light. Both lean red, so they'll behave similarly in mixed or changing light conditions. With a ΔE of 30.2, 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 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.

5 real rooms side by side. Seeing Cinnamon Slate and Onyx 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 Cinnamon Slate will make the room feel meaningfully brighter than Onyx would.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. Cinnamon Slate reflects noticeably more light off the walls, making the space read more open than Onyx.
Bathroom

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. Cinnamon Slate reflects noticeably more light off the walls, making the space read more open than Onyx.
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 Cinnamon Slate will make the room feel meaningfully brighter than Onyx would.
