Black paint is bold, beautiful, and surprisingly nuanced. If you’re torn between Sherwin-Williams Black Magic and Benjamin Moore Onyx, you’re not alone — both are beloved for their depth and elegance. But they’re not the same. Here’s a side-by-side breakdown to help you decide which one deserves a place in your home.

BLACK MAGIC VS ONYX

🖤 Black Magic – Sherwin-Williams (SW 6991)

The Look:

Black Magic is rich, warm, and velvety. It’s not jet black — instead, it has a slightly soft edge that brings warmth and luxury into a space.

Light Reflectance Value (LRV): 3

Undertones: Subtle warmth (without looking brown or muddy)

Best for: Bedrooms, living rooms, cabinetry, moody dining rooms

Pairs beautifully with: Creamy whites, wood tones, brass or gold accents

Why You’ll Love It:

Black Magic adds drama, but it’s easier on the eyes than colder blacks. It works wonders in cozy, intimate spaces where you want depth without stark contrast.

🖤 Onyx – Benjamin Moore (2133-10)

The Look:

Onyx is a clean, true black. It’s darker and slightly cooler than Black Magic, with a crisp finish that’s ideal for high-contrast designs.

Light Reflectance Value (LRV): 4.99

Undertones: Neutral-to-cool

Best for: Trim, front doors, accent walls, modern cabinetry

Pairs beautifully with: Crisp whites, steel, chrome, high-contrast interiors

Why You’ll Love It:

Onyx delivers sleek, modern drama. If you're going for bold and graphic, this is your black. It holds up beautifully in both natural and artificial lighting.

Final Verdict:

Choose Black Magic if you want a rich, velvety black that feels warm and intimate. It's perfect for cozy interiors and subtle sophistication.

Choose Onyx if you want a pure, neutral black that makes a strong, clean statement.
