Can a Color Be a Trademark? Le Creuset’s Orange and the Legal Requirements for Color Mark Registration

In 1995, the United States Supreme Court confirmed that a single color can function as a trademark. The decision in Qualitex Co. v. Jacobson Products Co. established the legal framework under which Le Creuset’s Flame orange, Tiffany’s robin’s egg blue, UPS’s package brown, and Christian Louboutin’s red sole have been registered and enforced as intellectual property. Yet the conditions under which color qualifies for trademark protection are demanding, and the boundaries of that protection continue to be tested in litigation. This article examines the legal requirements for color mark registration and the business rationale and costs associated with pursuing this unusual form of intellectual property protection.

Qualitex v. Jacobson Products: The Constitutional Moment for Color Marks

Before 1995, the prevailing view in U.S. trademark law was that single colors could not serve as trademarks, partly because of concerns about competitive depletion—the idea that allowing one company to monopolize a color could unfairly restrict competitors’ ability to distinguish their goods. The Supreme Court, in a unanimous decision authored by Justice Ginsburg, rejected this categorical position.

The case arose from Qualitex Company’s use of a distinctive gold-green color on its dry-cleaning press pads, used since the 1950s, and competitor Jacobson Products’ subsequent adoption of the same color. The Court held that the Lanham Act’s capacious reference to “any word, name, symbol, or device” encompasses color, and that a color can function as a trademark if it has acquired distinctiveness through secondary meaning and is not functional. The functionality doctrine—which bars trademark protection for features that are essential to the use or purpose of a product—was identified as the key limiting principle.

Qualitex also reaffirmed that color cannot be inherently distinctive; a color mark can only be registered upon proof of acquired distinctiveness (secondary meaning), meaning that consumers have come to associate the color with a particular source through long and exclusive use in commerce.

Le Creuset’s Flame Orange: Nearly a Century of Brand Color

Le Creuset, the French cast-iron cookware manufacturer founded in 1925, has used a distinctive orange it calls “Flame” since its founding year. Inspired, according to the company, by the appearance of molten iron being poured into molds, the color is described as progressing from a deeper to a lighter shade of orange to produce a flame-like visual effect.

In the United States, Le Creuset has registered the Flame color as a trademark for cookware and kitchen utensils, with the USPTO registration (including Registration No. 2164832 and related filings) describing the color mark in detail. European Union trademark registrations at the EUIPO further protect the brand’s color in key markets. The near-century of continuous commercial use, combined with the color’s prominent role in Le Creuset’s marketing and consumer recognition, satisfies the secondary meaning requirement across jurisdictions.

The non-functionality requirement is also met: the orange color serves no functional purpose intrinsic to the performance of cast-iron cookware. A pot of any color would function identically; the orange serves exclusively as a source identifier. This contrasts with cases where color correlates with functional properties—such as the color-coding of electrical wiring gauges—where trademark protection would be unavailable.

Tiffany Blue, UPS Brown, and Coca-Cola Red

The landscape of registered color marks in the United States includes several widely recognized examples. Tiffany & Co. has registered its distinctive robin’s egg blue (identified as Pantone 1837, a number chosen to match the company’s 1837 founding year) as a U.S. trademark for jewelry, packaging, and related goods. The Tiffany Blue box has been a consistent element of the brand’s presentation since the nineteenth century, producing the level of consumer association that satisfies the secondary meaning standard.

United Parcel Service has registered a specific shade of brown (Pantone 469) as a U.S. trademark for delivery and logistics services. The company’s slogan “What can Brown do for you?” explicitly referenced the trademark in commercial communication. The color appears on UPS vehicles, uniforms, and packaging, and consumer recognition of the brown as a UPS identifier is well-established in surveys.

The Coca-Cola brand uses a distinctive red across its packaging, vending machines, and advertising materials, registered as a color mark for soft drinks. The competitive dynamic in the carbonated beverage sector—Coca-Cola red versus Pepsi blue—illustrates how color marks can function as the primary differentiator in mature consumer product categories.

Louboutin v. Yves Saint Laurent: The Boundaries of Color Mark Protection

The most consequential litigation over the scope of color trademark protection in the fashion sector is Christian Louboutin S.A. v. Yves Saint Laurent America, Inc., 696 F.3d 206 (2d Cir. 2012). Christian Louboutin began applying a distinctive lacquer red to the outsoles of women’s high-heeled shoes in 1992, and obtained a U.S. trademark registration (Registration No. 3361597) in 2008 covering “a lacquered red sole on footwear.”

The dispute arose in 2011 when Yves Saint Laurent released a line of monochromatic red pumps—shoes where the sole, upper, and all other visible surfaces were red. Louboutin asserted trademark infringement; YSL moved to cancel Louboutin’s registration, arguing that the color red was functional (aesthetically essential to fashion design) and that the registration was improperly granted.

The Second Circuit’s September 2012 ruling drew a nuanced distinction. The court upheld Louboutin’s red sole mark as valid in contexts where the red sole contrasts with a different-colored upper—the characteristic appearance of most Louboutin shoes. However, where the entire shoe, including both the upper and the sole, is red, the court declined to extend Louboutin’s trademark rights. The rationale was that in a monochromatic shoe, the red sole does not function as a distinctive source indicator separable from the overall color of the shoe.

This “contrasting color” limitation has been widely cited in subsequent color mark cases as an illustration of how courts calibrate the protection to the specific commercial context in which the mark has acquired distinctiveness, rather than granting protection that extends beyond that context.

Japan’s Color Trademark System: 2015 Reform and Registration Practice

Japan did not recognize single-color trademarks until the Trademark Act was amended in 2014 (entering into force on April 1, 2015). Before the amendment, the Act required that a mark have some defined form—a character, figure, three-dimensional shape, or combination thereof—which excluded single colors or color combinations per se.

The amended Act created a category of “trademark consisting solely of a color” (色彩のみからなる商標). Registration requires a showing of acquired distinctiveness through evidence of long and exclusive commercial use—a parallel to the U.S. secondary meaning requirement. Applicants must submit documentation of the duration and geographic scope of use, sales volumes, marketing expenditures, and consumer recognition surveys to establish that the color has come to identify the applicant’s goods or services.

Among the earliest color-only registrations in Japan is Seven-Eleven Japan’s orange-green-red stripe combination, registered as a trademark for convenience store services. Tombow Pencil’s blue-white-black horizontal band on its MONO erasers is another registered example. As of the mid-2020s, registrations remain limited in number, and the examination process involves significant substantive review that creates barriers to rapid acquisition.

The Business Case and Its Costs

A successfully registered color trademark provides a powerful competitive instrument: it can prevent competitors from using the same or similar color for the same category of goods or services, creating a durable, legally enforced association between the color and the brand. In a market environment where visual recognition can influence purchasing decisions before a consumer reads a label or brand name, a color that exclusively identifies one company is commercially valuable.

The costs, however, are substantial. Establishing secondary meaning requires years of consistent and exclusive use in commerce before filing—any early departure from the color undermines the accumulation of consumer recognition. Professional fees for trademark prosecution, opposition proceedings, and maintenance filings add up over the life of the mark. Ongoing surveillance and enforcement against unauthorized use are prerequisites for maintaining the mark’s validity and legal force.

Perhaps the largest cost is strategic: color trademark ownership invites challenge. Competitors who wish to use similar colors in adjacent product categories have strong incentives to attack the registration’s validity on secondary meaning or functionality grounds. The Louboutin litigation illustrates how a well-established color mark can still face determined challenge from a sophisticated opponent with significant litigation resources. Companies seeking color marks must be prepared for a long-term commitment to both acquisition and defense.

Le Creuset’s Flame orange represents one of the clearest cases where this commitment has paid off. A century of consistent use, a color distinctive enough to be immediately associated with the brand across global markets, and a product category where the color serves no functional purpose other than source identification: these conditions have made the Flame trademark a defensible and valuable component of a brand portfolio that extends well beyond any single product.
