What Is Benjamin Moore Color Lock® Technology?

If you’ve ever picked up a can of Benjamin Moore Aura® and noticed “Color Lock® Technology” on the label, it’s natural to wonder: What does that actually mean and does it matter for your project? As an independent C2 dealer at US Paint Supply, we work with customers who are comparing top-tier paints all the time. In this article we’ll unpack Color Lock in plain language, explain why Benjamin Moore developed it, where you’ll actually find it, and how it compares to ultra-premium options like C2 LUXE and other high-end paints.

Color Lock in Plain English

Benjamin Moore describes Color Lock as a technology that "locks" pigments into the paint film so colors stay richer, resist fading, and don’t rub off even after repeated washing. In reality, it’s a proprietary acrylic resin added to their colorants.

Put simply: the goal is to build a tougher paint film that holds onto color, especially in deep, saturated shades and in rooms that get scrubbed or see a lot of wear.

Why Color Lock Was Needed in the First Place

To understand why Color Lock exists, it helps to look at how conventional tinting systems behave.

How colorants weaken paint

Most big paint brands historically used “universal” colorants—additives that can tint both solvent-based and water-based paints. Those colorants often include ingredients that:

• Thin the paint and lower viscosity.
• Make it harder for the dry film to stand up to scrubbing and washing.
• Can lead to color rubbing off onto a cloth or sponge, especially in darker shades.

Benjamin Moore has publicly said that durability with conventional colorants tends to drop as the color gets deeper, because the extra colorant brings along components that weaken the film. That’s a problem if you love rich blues, charcoal greys, or near-black colors in high-traffic areas.

The Gennex® colorant system

Benjamin Moore’s answer was to design its own waterborne colorants(Gennex) that are engineered specifically for their paints. By removing many of the ingredients that weaken paint, Gennex lets even deep colors keep similar durability and washability to whites and off-whites.

How Color Lock Technology Works (Simplified)

You’ll see slightly different marketing explanations, but the core idea is consistent across manufacturer and dealer sources:

• Pigments are encapsulated inside the paint film by proprietary resins and binding molecules, rather than just sitting loosely in the film.
• Special polymers wrap around the color particles as the paint dries, creating a thicker, denser film that dries harder and is less sensitive to humidity and moisture.

Think of it like this:

Normal paint: pigment particles are mixed into the film, but under heavy scrubbing or repeated washing, some of that color can migrate to your rag.

Color Lock paint: pigment particles are more “embedded” in a web of resin, so when you scrub, you’re mostly removing surface dirt rather than the color itself.

What you actually notice on the wall

On a real project, any paint systems that use resins in their colorants/tints translates into:

• Better washability in dark colors – repeated cleaning without obvious color rub-off.
• Fade resistance – improved protection against UV and chalking, particularly in Aura Exterior.
• High hide in tough colors – thicker, high-solids films that often cover deep color changes in fewer coats than standard premium paints (assuming good prep and primer where needed).
• Resistance to scuffing and burnishing – a big deal in hallways, kids’ rooms, and tight spaces.

Where You’ll Actually Find Color Lock or Matched Pigment Resins

Color Lock is not in every Benjamin Moore product. It’s specifically tied to the Aura family:

• Aura Interior – Benjamin Moore’s ultra-premium interior line; the official product page calls out “exclusive Color Lock technology” for long-lasting color depth.
• Aura Exterior – uses a new acrylic resin plus Color Lock to embed pigment in the film, improving fade resistance and reducing chalking on exteriors.
• Aura Bath & Spa – a matte, bathroom-specific coating that pairs Color Lock with a mildew-resistant, high-humidity formulation.
• Various other brands

Benjamin Moore and multiple dealer sites emphasize that Color Lock is available only in Aura-brand paints, not in Regal Select, ben®, or other lines (those use Gennex colorants but rely on different feature technologies like stain release). So if “Color Lock” is the specific feature you’re after, you’re really shopping within the Aura family.

When Does Color Lock Actually Matter for Your Project?

Color Lock is a real technology—but that doesn’t mean everyone needs it on every job. Here’s where it tends to make the most sense:

Great use cases

• Dark and very saturated colors Deep navies, charcoals, forest greens, and bold accent walls are where conventional paints are most likely to show rub-off, uneven touch-ups, or early fading. Color Lock is designed specifically to keep those colors rich and even.
• High-traffic interiors Hallways, mudrooms, entryways, kids’ rooms, and busy family spaces that get bumped, touched, and cleaned often.
• Bathrooms and spas High humidity plus frequent cleaning is hard on paint. Aura Bath & Spa uses Color Lock plus a humidity-tolerant matte film to stay rich and washable.
• Sun-exposed exteriors On south- or west-facing walls, Aura Exterior’s combination of Color Lock and a specialty exterior resin is engineered for better UV and fade resistance than more basic exterior lines.

Where Color Lock may be “nice to have” rather than essential

• Light, forgiving colors in low-wear rooms – Soft whites and light greys in guest rooms or home offices see far fewer scrub cycles; a standard premium like Benjamin Moore Regal Select or an ultra-premium independent brand like C2 Studio can be entirely appropriate.
• Budget-sensitive projects – If you’re painting a rental turnover in off-white and mainly need decent coverage and speed, Aura’s price premium isn’t always necessary.

In all cases, remember that prep and primer still matter. If you’re covering stains, smoke damage, or heavy color changes, the primer you choose will often be as important as the topcoat.

Does Any Other Brand Use the “Same” Technology?

Yes. It's difficult to say who brought this to market first, but this technology is in active use by other brands, and has been for quite some time.

• “Color Lock®” is Benjamin Moore’s proprietary technology and brand name. It’s only used in Aura Interior, Aura Exterior, and Aura Bath & Spa.
• Other manufacturers don’t license or advertise Color Lock. They use their own advanced resins and custom colorant systems.
• Specifically, C2 Paint has been using Resin matched colorants for decades.
