Colour Bleeding: The Hidden Challenge of Leather Quality

Leather is prized for its beauty, texture and durability. But there’s a silent problem that can ruin even the most luxurious piece: colour bleeding.

Colour bleeding happens when the dye used in leather isn’t fully fixed or protected. The result? Vibrant leather loses its integrity shades rub off on hands, clothing or even other leather products. It’s not just unsightly; it’s a mark of poor craftsmanship.

Why Colour Bleeding Happens

• Incomplete Dye Fixation: If the pigments or dyes don’t fully bond with leather fibers during tanning or finishing, they remain unstable.

• Excess Moisture Exposure: Water, sweat or even high humidity can loosen dyes that haven’t been properly fixed, causing transfer or smudging.

• Poor Quality Top-Coating: Without a protective finish or sealant, the surface pigments are vulnerable to friction, abrasion or rubbing.

• Low-Quality Dyes: Some dyes are cheap or environmentally unsafe; they may look vibrant initially but fail under real-life conditions.

The Role of Colour Fastness

The solution to colour bleeding lies in colour fastness—the ability of leather dyes to resist fading or running when exposed to factors like rubbing, water, sweat, and light.

At Om Leather Artdeco, colour fastness isn’t just a quality check, it’s a benchmark. We align our processes with ISO international standards, which define how colour fastness is measured and rated.

How it’s measured (ISO Standards):

• ISO 11640 – Colour fastness to rubbing: Evaluates how much colour transfers to white fabric under dry and wet rubbing.

• ISO 11641 – Colour fastness to perspiration: Tests how leather reacts when exposed to artificial sweat.

• ISO 11642 – Colour fastness to water spotting: Measures dye stability against water contact.

• ISO 105-B02 – Colour fastness to light: Determines how dyes resist fading when exposed to artificial light sources.

Results are rated on a scale from 1 to 5 (sometimes extended to 8 for light fastness), where 1 = poor and 5/8 = excellent. For premium leather, only ratings of 4 and above are acceptable.

How We Combat Colour Bleeding

At Om Leather Artdeco, we treat colour bleeding as a serious challenge, not an afterthought. Here’s how we tackle it:

• High-Performance Dyes: Only pigments tested for stability, fastness, and resistance to moisture are used.

• Chemical Fixatives: Special agents lock dyes into the leather fibers, ensuring they don’t wash or rub off.

• Protective Finishing Layers: Multiple layers of top-coats protect the surface without compromising softness or texture.

• Rigorous Testing: We simulate real-world conditions—wet rub tests, dry rub tests, sweat exposure and light fastness—based on ISO protocols.

• Moisture & Storage Control: During production and storage, controlled humidity prevents any chance of bleeding before the leather reaches the customer.

Why It Matters

Colour bleeding is more than cosmetic. It signals instability, weak bonding and subpar craftsmanship. For buyers, it’s a nightmare: ruined outfits, complaints and reduced trust in the product.

At Om Leather Artdeco, we see it as a problem to solve, not accept. Every piece of leather we deliver is tested to ensure its colour stays true—stable, rich and transfer-free even under the harshest conditions.

In leather, beauty is temporary. True quality is when the colour never bleeds, the finish never fails and the promise of durability is unwavering.
