Is Tiffany Blue Trademarked? The Story Behind the Iconic Color

Last updated: July 2026

Yes, Tiffany Blue is trademarked. Tiffany and Co. registered the robin’s egg blue shade as a color trademark in 1998, and it is standardized as a custom Pantone color, PMS 1837, named for the year the company was founded. Protection covers the brand’s boxes, bags, and packaging for jewelry and related luxury goods, not every use of light blue everywhere.

Is Tiffany Blue Trademarked?

Tiffany and Co. filed for federal trademark protection of Tiffany Blue in 1998 and successfully obtained registration in the United States. The color is now protected as a trademark in most major jurisdictions around the world. Unauthorized use of the shade in contexts that could cause confusion with Tiffany’s brand can result in legal action.

It is important to understand what the trademark does and does not cover. Tiffany does not own robin’s egg blue as such. The protection is limited to specific commercial applications, primarily the brand’s boxes, bags, and packaging materials in the jewelry and luxury goods sector. Tiffany can only enforce the mark where use of the color could reasonably confuse consumers about the source of the goods.

Where did the color come from?

The story of the color long predates the trademark. Charles Lewis Tiffany selected the distinctive light blue for the brand’s packaging in 1845, when it appeared on the cover of the company’s first Blue Book catalog of fine jewelry. The shade resembles the pale blue of a robin’s egg, which is why it is often called robin’s egg blue, and it quickly became the visual signature of the house.

By the twentieth century the little blue box had become one of the most recognizable objects in retail. Tiffany famously sells the box only with a purchase, a policy that reinforces the exclusivity of the packaging and, in trademark terms, the exclusivity of the color itself. Nearly two centuries of continuous, consistent use built the consumer association that made the 1998 registration possible.

Can a Color Be Trademarked at All?

Yes, in the United States and many other jurisdictions, a single color can function as a trademark. A color mark is classified as a non-conventional trademark, in which a color performs the core trademark function of identifying the commercial origin of goods or services.

The legal foundation in the United States was established by the Supreme Court in Qualitex Co. v. Jacobson Products Co. (1995), a dispute over the green gold color of dry cleaning press pads. Writing for a unanimous Court, Justice Stephen Breyer explained that color alone, at least sometimes, can meet the basic legal requirements for use as a trademark, because it can act as a symbol that distinguishes a firm’s goods and identifies their source without serving any other significant function.

Two conditions do the heavy lifting. First, the color must have acquired distinctiveness, known as secondary meaning: consumers who see the color in the relevant market must think of one specific brand. Second, the color must not be functional. A color that affects the cost, quality, or performance of the product, or that competitors need for practical reasons, cannot be monopolized. Qualitex opened the door for brands like Tiffany to register colors that had built decades of exclusive association.

How do different countries treat single color trademarks?

International standards vary significantly by jurisdiction.

• United States: Single color marks are permitted since Qualitex (1995), on proof of secondary meaning and non-functionality.
• European Union: Under the EU Trade Mark Implementing Regulation, Article 3(3)(f), color marks are registrable, but the Court of Justice held in the Libertel case (C-104/01) that a color is not normally inherently distinctive. Applicants must prove acquired distinctiveness through extensive and exclusive use.
• Australia: Section 6 of the Trade Marks Act 1995 expressly includes color in the definition of a sign. Single colors usually still require evidence of acquired distinctiveness because they have low inherent distinctiveness.
• Argentina: Under Law No. 22.362, a single color standing alone generally cannot be registered. Protection is possible where an arbitrary color is combined with a distinctive shape or packaging and the shade is precisely specified, for example by a Pantone code. On that framework, Tiffany Blue applied to the brand’s boxes would likely qualify, since it is an arbitrary color identified as Pantone 1837.

What is the color depletion theory?

The color depletion theory, also called color exhaustion, is the main policy objection to color trademarks. The spectrum of usable colors is limited, and each color serves functional and aesthetic purposes across industries. If too many companies obtain exclusive rights to individual colors, the available palette for competitors and new entrants shrinks, restricting competition and creativity.

The concern is especially acute in fashion, where color is not merely decorative but fundamental to the product. Designers rely on color as a primary tool of expression and differentiation, so trademark authorities must balance the legitimate interest of established brands in protecting identity against the public interest in a competitive, creative marketplace. The answer courts have settled on is scope: no brand owns a color outright, only a color applied to a narrow commercial context.

What is the shade confusion doctrine?

A second challenge is shade confusion: courts and consumers may struggle to tell similar shades apart, which risks overbroad protection. In American practice this is handled through the likelihood of confusion test, asking whether consumers would mistake the source of goods based on the similarity of the colors used.

Precise registration mitigates the problem. When the protected shade is fixed against an objective standard such as a Pantone code, owners and courts have a benchmark for deciding whether an accused use involves the same color or a meaningfully different one. Tiffany’s Pantone 1837 designation is a textbook example. Even so, outcomes vary internationally: Christian Louboutin’s red sole has won protection in some jurisdictions and faced limits in others, showing that a shade protected in one country may be refused in the next.

What Is Pantone 1837?

Pantone 1837, also written PMS 1837, is the official standardized designation of Tiffany Blue on the Pantone Matching System. The number is not sequential like ordinary Pantone codes; it commemorates 1837, the year Charles Lewis Tiffany founded the company in New York.

Pantone created the shade as a custom, private color for Tiffany. It does not appear in the standard Pantone swatch books sold to designers and printers, and the exact formulation is not commercially available to the general public. This controlled distribution serves the trademark: it keeps the precise shade exclusive to Tiffany’s own packaging and marketing, and it gives courts an objective reference point when the company enforces its rights.

The proprietary shade is a light medium tone of blue with a hint of green, distinct in its exact values from the generic robin’s egg blues that remain free for other brands and designers to use.

How Does Tiffany Enforce the Color?

Tiffany protects the color through a combination of registration, supply control, and active policing. The trademark registrations cover the shade as applied to boxes, bags, catalogs, and related packaging for jewelry and luxury goods. The custom Pantone arrangement keeps the exact formulation out of general circulation, and the company’s policy of never selling an empty blue box preserves the link between the color and a genuine Tiffany purchase.

Enforcement in practice typically means cease and desist letters, oppositions to conflicting trademark applications, and, where necessary, infringement litigation against sellers of counterfeit or confusingly packaged goods. Because the mark is limited by the likelihood of confusion standard, Tiffany’s strongest cases involve jewelry, watches, and adjacent luxury categories. A bakery or a paint company using a similar blue is unlikely to confuse anyone about the source of a diamond ring; a jewelry seller shipping rings in robin’s egg blue boxes is a different matter. The company has also litigated vigorously over its word mark, including its long dispute with Costco over rings sold using the name Tiffany, which although not a color case reflects how aggressively the brand defends its identity.

Tiffany has defended color trademarks beyond its own. Together with the International Trademark Association, Tiffany filed amicus curiae briefs supporting Christian Louboutin’s claim to the red sole in its litigation against Yves Saint Laurent, arguing that denying protection to a single color that has achieved secondary meaning would be unfair and inconsistent with fundamental trademark principles, and that fashion deserves careful treatment precisely because color is central to brand identity in the industry.

Why does color branding work so well?

We identify brands through distinctive shortcuts. Apple has the bitten apple, Starbucks the green siren. Some brands are identified in the public mind by a single color alone. For Tiffany, the sight of a robin’s egg blue box signals luxury jewelry, engagement rings, and the heritage of the house before a single word is read. When a color reaches that level of secondary meaning it stops being decoration and becomes a source identifier, which is exactly what trademark law exists to protect.

Which Other Brands Own Color Trademarks?

Tiffany is in select company. A handful of brands worldwide have secured or asserted trademark rights in a single color for a defined commercial use.

Hermes orange packaging is another well known example of a color closely tied to a luxury house. The common thread across all of these marks is scope: Louboutin’s rights cover the sole of a shoe, not red shoes generally; Cadbury’s purple covers chocolate packaging, not purple products at large; Tiffany’s blue covers jewelry packaging. Narrow scope is what keeps color trademarks compatible with the depletion concerns discussed above.

Frequently Asked Questions

What is the exact Pantone color of Tiffany Blue?

Tiffany Blue is officially designated Pantone 1837 Blue, named after the founding year of Tiffany and Co. It is a custom, proprietary Pantone formulation that is not included in standard swatch books and is not available for commercial purchase by the general public.

Can I use Tiffany Blue for my own products or packaging?

Using Tiffany Blue or a confusingly similar shade for jewelry, luxury goods packaging, or related products could constitute trademark infringement. Tiffany’s rights are limited to contexts where the color could cause confusion with its brand, so use in unrelated industries or for non-commercial purposes may not infringe. Businesses should consult trademark counsel before adopting the shade commercially.

When did Tiffany and Co. start using Tiffany Blue?

Charles Lewis Tiffany chose the robin’s egg blue for the brand’s packaging in 1845. The company has used the shade continuously ever since, and that record of exclusive use supported its federal trademark registration in 1998.

What case made color trademarks legal in the US?

Qualitex Co. v. Jacobson Products Co., decided by the Supreme Court in 1995. The Court held unanimously that a color alone can be registered as a trademark if it has acquired secondary meaning and is not functional. Tiffany registered its blue three years later.

Why is it difficult to trademark a color?

Colors usually lack inherent distinctiveness and often serve functional or aesthetic purposes rather than identifying source. Applicants must prove acquired distinctiveness through extensive exclusive use, and offices weigh the color depletion theory, the concern that granting too many color monopolies would unfairly restrict competition, particularly in fashion where color is essential to design.
