The short version
- A single colour can be registered as a trademark in the US, the UK and the EU, but only when the public already links that colour to one brand in one context.
- The US Supreme Court confirmed in Qualitex v. Jacobson (1995) that colour alone can be a trademark once it has acquired secondary meaning.
- Cadbury lost its bid to register a purple in 2013 because the application described the colour as merely predominant, which the Court of Appeal found too vague.
- A colour that does a practical job, such as signalling safety or hiding dirt, cannot be owned as a trademark because competitors need it too.
- For most brands, a specific combination of colours, materials and type is easier to make recognisable than a single colour is to register.

Can you trademark a color? Yes, but rarely, and usually only after years of use. In the US, the UK and the EU a single colour can be registered when the public already sees it as a sign of one brand in one setting, and when the colour does no practical job. Tiffany's blue boxes and Owens Corning's pink insulation passed that test. Cadbury's purple, famously, did not. This is a plain overview of documented cases, not legal advice: for your own brand, speak to a trademark attorney in your country.
What a colour trademark actually protects
A trademark never protects a colour everywhere. It protects a colour used on particular goods or services, so that customers are not confused about who made them. Tiffany's registration covers its blue on boxes, bags and similar packaging, not every blue object in the world. A florist can still paint a shop door that colour; a rival jeweller selling rings in near identical boxes is a different matter.
Famous colour trademark examples
A handful of cases come up again and again because they set the rules. Each one is widely reported; the details below stay with what is on the public record.

Why Cadbury lost its purple
Cadbury had used its purple on chocolate wrappers for decades, and few people doubt that shoppers associate the two. The problem was the wording. The application covered purple as the predominant colour of the packaging, which could mean many different looks. The Court of Appeal in England and Wales ruled in 2013 that a trademark must be clear and precise, and a colour that might be predominant in countless arrangements was neither. Recognition alone was not enough.
Why Tiffany kept its blue
Tiffany's case is the opposite: one specific shade, used consistently on one kind of object, for a very long time. The colour was later standardised as a custom Pantone shade, so there is no doubt about which blue is meant. Precision and consistency are what made it ownable.
Why trademarking a colour is so hard
Courts are reluctant to let one company take a colour out of circulation. There are only so many distinguishable hues, and a market where each one belongs to someone would be unworkable. So a colour applicant usually has to clear four hurdles at once.
- 1
Acquired distinctiveness
A colour is not seen as a brand sign by default. You normally need evidence, such as years of use, advertising and surveys, that the public links it to you.
- 2
No practical function
If the colour does a job, it stays free. Safety orange, or a colour chosen because it hides wear or makes a product look smaller, is not ownable, because rivals need it too.
- 3
Precise description
Name the exact shade, often with a recognised colour code, and exactly how it appears on the product. Cadbury shows what vagueness costs.
- 4
One context
The colour must point to you in a defined category. Owning magenta for telecoms says nothing about magenta lipstick.
What smaller brands can realistically own
For a new or small brand, chasing a single colour trademark is usually the wrong fight. The evidence of recognition takes years to build, and your category probably already shares its favourite colours. What you can build, from the first post, is a combination that nobody else uses: a ground, a family of colours, a texture and a type voice that always appear together. That idea is covered in depth in distinctive brand assets.
Hard to own
- One popular hue, such as a bright blue
- A colour your whole category uses
- A colour that signals a function
- Changing shades every season
Realistic to build
- A specific ground with two or three companions
- A material: grain, sheen, paper or glass
- The same type voice on every piece
- Years of using it without changing it
One colour family, one material, one type voice, repeated on every post.
The same look in a story. Recognition comes from the whole combination, not one swatch.
Consistency is what turns a look into an asset, so it helps to write it down. A brand style guide that names your exact colours, and a habit of brand consistency across every channel, do more for recognition than any filing in the first few years.
Owning a look on Gradiently
Gradiently approaches the same problem from a different side. Each Mark is a complete look: colours, up to three materials, light, grain, motion and a type voice. Every Mark is checked against every other, anything too close is refused, and each has exactly one owner at a time. When you claim one, your name goes on its public record with a numbered certificate, and only you can export designs with it. That is a Gradiently registry record, not a trademark, so it does not stop anyone outside Gradiently from using similar colours. What it gives you is a look nobody else on the platform can publish, from day one. What is a Mark explains the details.

Brass Reflection
See this MarkQuestions people ask
Can you trademark a color?
Yes, in the US, UK and EU, but only when the public already links that exact colour to your brand for specific goods, and the colour does no practical job.
Is Tiffany Blue trademarked?
Yes. Tiffany & Co. registered its robin's egg blue as a US trademark in 1998 for use on items such as its boxes and bags.
Why did Cadbury lose its purple trademark?
In 2013 the Court of Appeal ruled that describing purple as the predominant colour of the packaging was not clear or precise enough to register.
Can I use a colour that another company has trademarked?
Usually yes, outside the goods and services the registration covers, as long as customers would not be confused. In the same category, take legal advice first.
Is owning a Mark on Gradiently the same as a trademark?
No. Owning a Mark is a record in Gradiently's registry that makes you its only owner on the platform. It is not a trademark and has no legal effect outside Gradiently.
