Let me share what makes two distinct black paint colors stand out across multiple industries.
Having used both Benjamin Moore’s Onyx and Black, I’ve seen these shades make their mark in homes, car finishes, and fashion design.
I’ll explain why certain luxury car brands pick Onyx’s neutral depth for their signature finishes, while others opt for Black’s subtle cool tones.
From living room walls to evening wear and custom car paint to statement furniture – these two blacks create notably different effects.
In this side-by-side look, we’ll examine how each shade shows up across different materials, lighting conditions, and uses.
Whether you’re planning to paint a room, thinking about a car repaint, or interested in color theory in fashion, you’ll see exactly what sets each black apart.
Understanding the Colour
Let’s start with the basics of what makes these two blacks different – it’s more interesting than you might think.
Benjamin Moore Onyx 2133-10 has a Light Reflectance Value (LRV) of 4.99, while Benjamin Moore Black 2132-10 sits slightly darker at 4.56 LRV.
Though this difference seems tiny, it creates notable variations in how each color appears in real life.
Basics About Onyx
- Onyx carries a wonderfully balanced character – imagine a black that doesn’t lean too warm or too cool. When I opened my first can of Onyx, I noticed it looked almost charcoal-like when wet, but it dried to a rich, pure black.
- It is special because it maintains its neutral stance under different lights.
Basics About Black
- On the other hand, Benjamin Moore Black brings subtle blue notes to the party. Think of it as the black that adds a bit more drama.
- Its slightly lower LRV means it absorbs more light, making it appear a touch deeper than Onyx.
I find these technical details fascinating because they explain why two seemingly similar blacks can look so different when applied. The numbers tell us what our eyes might miss at first glance – Onyx offers more light play, while Black creates more depth.
Comparison Between Black & Onyx
When put side by side, these blacks show their true colors, so to speak. Let’s break down the key differences I’ve noted through my projects and research.

- Pure Black Tends to spark strong initial reactions. Some people find it bold and definite, while others might feel it’s too stark. It commands attention and makes a clear statement about boundaries and strength.
- Onyx Colour Creates a more subtle emotional impact. Its slight softness helps people feel more at ease, similar to how a dark grey blanket might feel more comforting than a pitch-black one. in home settings, many find it less imposing while still maintaining visual impact.
Cultural Significance and Meanings
Pure black carries deep cultural weight across societies. It often represents:
- Authority and power in business attire

Onyx, as a natural stone, connects to different cultural threads:

In modern homes, these meanings still echo. A pure black wall might create a sense of authority in a home office, while an onyx-colored feature could bring a feeling of natural stability to a living space. The choice between them often comes down to the emotional atmosphere you want to create.
Think of It This Way: black is like a period at the end of a sentence – clear and final. Onyx works more like an ellipsis… suggesting there’s more to see and feel.
