How colour trade marks work in Australia, registration, distinctiveness and the disputes they spark

A colour can be a trade mark in Australia. The Trade Marks Act 1995 (Cth) expressly includes colour in its definition of a "sign", and IP Australia will register a colour mark where the colour genuinely identifies one trader's goods or services. But the scheme is deliberately stingy. A single colour has no natural tendency to point to any particular business, so the law demands proof that the colour has come to mean your brand before it will grant a monopoly over it.

That combination is what most businesses miss. The mechanism sounds simple: file an application, describe the colour, register it, enforce it. In practice each stage carries a distinct test, and the case law shows that even enormous brands have fallen at the last hurdle. This guide walks through the scheme end to end: who is involved, how a colour gets from application to registration, and where the real disputes tend to break out.

Who does what in a colour trade mark

Four actors matter in a colour mark:

The applicant: Usually the business itself, filing in its own name. It must nominate the goods or services the colour will protect, describe the colour precisely, and if the colour is not inherently distinctive, bring evidence of use.
IP Australia: The government agency that examines applications. Its examiners decide whether a colour is capable of distinguishing the applicant's goods or services, and its delegates hear oppositions. Its published manual of practice and procedure sets out how colour marks are assessed.
Competing traders: Anyone can oppose a colour mark after it is accepted. Competitors also drive the disputes that matter: they oppose registrations, and they are the ones allegedly copying colours.
The Federal Court: Appeals from examiners and oppositions, and infringement and consumer law proceedings, all end up here. The judge, not the examiner, makes the final call on registrability in an appeal, hearing the evidence afresh.

The tension is structural. The applicant wants a monopoly over a colour it has invested in. Every other trader wants the freedom to use colours that are useful, attractive or conventional in the same market. The Trade Marks Act resolves that tension through the distinctiveness test, which is the single most important part of the scheme.

Why a colour can be a trade mark at all

The starting point is the definition of a trade mark in s 17 of the Trade Marks Act 1995 (Cth): a sign used, or intended to be used, to distinguish goods or services dealt with in the course of trade by one person from those of any other person. Section 6 defines "sign" to include "any letter, word, name, signature, numeral, device, brand, heading, label, ticket, aspect of packaging, shape, colour, sound or scent".

The Federal Court confirmed what this means for colour in Philmac Pty Ltd v Registrar of Trade Marks [2002] FCA 1551. Philmac made rural polyethylene irrigation fittings and wanted to register the terracotta colour applied to the connecting inserts of its fittings. The Court held that a colour applied to part of a product could, in principle, be a sign and therefore a trade mark. There was no need for the colour to be used alongside a logo or a word; the colour itself could do the distinguishing work.

That is the doorway. The difficult question, which the same case illustrates, is whether a particular colour actually does distinguish in practice. A word mark like "Telford" or a distinctive logo is easy to register because it has nothing to do with the goods. A colour is different: it is part of how almost every product is made and sold.

The first hurdle: proving the colour distinguishes

Section 41 of the Trade Marks Act 1995 (Cth) requires an application to be rejected if the trade mark is not capable of distinguishing the applicant's goods or services from those of other persons. In deciding that question the Registrar first considers the extent to which the mark is inherently adapted to distinguish. That is where single colours start in trouble.

A plain colour has little or no inherent capacity to distinguish. Green is green; it does not by its nature signal any particular source of petrol, lettuce or paint. The courts have treated colours as capable of registration only through acquired distinctiveness: the colour must have come, in the minds of consumers, to identify the applicant's goods or services, usually through extensive use before the application is filed.

The evidence an applicant needs is therefore practical rather than legal. IP Australia looks for proof that the colour was used as a badge of origin: consistent application to the goods or their packaging, the length of time the colour has been in the market, sales figures, advertising spend, media coverage, and ideally survey or consumer recognition evidence showing people associate the colour with the applicant. Under s 41, use by a predecessor in title counts as use by the applicant.

Two further features of the test matter for applicants:

Functional or common colours are nearly impossible: If the colour does a job rather than identifying a brand, registration is very hard to justify. Safety colours, colours dictated by industry convention, or colours that all traders in the field need (the yellow used across discount retailing is a classic example) are treated as functional or descriptive, and the law is reluctant to give one trader a monopoly over them.
The evidence must relate to use of the colour as a mark: Woolworths Ltd v BP plc [2006] FCAFC 132 is the cautionary tale. BP had used green on its service stations for decades and a single judge had allowed its applications for the colour green, but the Full Court held the evidence did not establish that the green distinguished BP's services as a trade mark, and that amendments BP had made to the applications' descriptions substantially changed the identity of the marks. The registrations did not survive. If the colour is always used as part of a wider get-up with logos and other elements, the evidence has to show consumers nonetheless read the colour itself as pointing to the business.

Philmac shows the flip side. On the strength of about seven years of consistent use of terracotta inserts in a niche market, the Court found the colour was capable of distinguishing and ordered registration. The colour mark was real, but it was won on evidence, not asserted.

Filing the application: representation, description and classes

If the colour clears the distinctiveness threshold in principle, the mechanics of the application become critical. Under reg 4.3(7) of the Trade Marks Regulations 1995 (Cth), an application for a colour, shape, scent or sound mark must include, in addition to a representation of the mark, a concise and accurate description of it.

Precision is not optional. In the Philmac litigation the Court would not allow the mark to be registered until the description pinned the exact shade: the final description read "the colour TERRACOTTA (PMS 484c +/- 10% *Lab, when observed under a controlled D65 illuminant), applied to the connecting inserts of the goods". A Pantone or similar colour reference, ideally with a tolerance and measurement conditions, tells competitors exactly what they cannot use. A vague description like "green" either gets rejected for uncertainty or produces a registration that is hard to enforce and easy to design around.

Two other drafting choices shape the scope of protection:

Goods and services classes: Protection runs only to the goods or services nominated. A colour registered for food packaging does not automatically cover clothing. Choosing the right classes, and the right wording within them, is part of the strategy.
Limitations as to colour: Under s 70 of the Trade Marks Act 1995 (Cth), a trade mark can be registered with limitations as to colour, and a mark registered without limitation is taken to be registered for all colours. This cuts both ways. A logo mark filed in black and white covers the logo in any colour, which is usually a broader and cheaper form of protection than a standalone colour mark. Conversely, the colour mark itself should be limited to the precise shade and manner of use that the business actually employs.

Examination, opposition and registration

Colour marks do not get a special process. They travel the same route as any trade mark, with closer scrutiny along the way.

The Registrar examines the application under s 31 of the Act and must accept it under s 33 unless satisfied there are grounds for rejection. For a colour mark the examination typically turns on s 41, but other grounds can bite: s 44 rejects marks that are substantially identical with, or deceptively similar to, an earlier registered mark, and s 43 catches marks likely to deceive or cause confusion. An adverse report will usually put the applicant to a choice: file evidence of acquired distinctiveness, narrow the specification or description, argue the point, or abandon the application.

If the application is accepted, it is advertised and third parties have a window to oppose under Part 5 of the Act. Opposition grounds mirror the rejection grounds and add more, including that the opponent has earlier use of a similar mark, that the applicant does not intend to use the mark, and since 2013, that the application was made in bad faith. An opposition is a formal proceeding with evidence and usually a hearing before a delegate of the Registrar, with appeals to the Federal Court.

Registration itself is routine once the application survives. The term is 10 years from the filing date under s 72, renewable in further 10-year blocks under s 77, the same as any other mark. What differs is the running cost of keeping the colour mark meaningful: distinctiveness can be lost if the colour is used inconsistently, licensed without control, or allowed to become generic in the trade.

Where colour disputes actually bite: infringement and consumer law

The enforcement side is where the "watch out" warnings in most colour trade mark commentary need the most correction. The law provides the tools, but Australian courts have consistently refused to let a brand own a colour in the abstract.

If a colour mark is registered, s 120 of the Trade Marks Act 1995 (Cth) gives the owner an infringement action against use of a sign that is substantially identical with, or deceptively similar to, the registered mark in relation to the registered goods or services (or similar ones). The comparison is not shade against shade in the abstract; it is how the colour is actually used, in context, and whether consumers would be deceived or confused.

Where there is no registered colour mark, or where registration is doubtful, the fallback is consumer law and passing off:

Section 18 of the Australian Consumer Law (Sch 2 to the Competition and Consumer Act 2010 (Cth)) prohibits misleading or deceptive conduct, and s 29 prohibits false or misleading representations. A look-alike colour scheme can breach these provisions if it misleads consumers about the origin of goods or services, even without any registered rights.
Passing off, preserved by s 230 of the Trade Marks Act 1995 (Cth), protects goodwill built up in a brand presentation against misrepresentation by a competitor.

The consistent lesson of the Australian cases is that these claims turn on the whole picture, not the colour in isolation:

In Cadbury Schweppes Pty Ltd v Darrell Lea Chocolate Shops Pty Ltd (No 4) [2006] FCA 446, Cadbury claimed Darrell Lea's use of purple in chocolate retailing misled consumers into thinking there was an association with Cadbury. The claim was dismissed. Cadbury's reputation in purple was real but not exclusive, other confectioners used purple, and consumers did not treat purple alone as identifying Cadbury.
In Verrocchi v Direct Chemist Outlet Pty Ltd [2016] FCAFC 104, the owners of Chemist Warehouse sued Direct Chemist Outlet over a yellow, red and blue storefront palette that closely tracked their own. The claim failed at trial and the Full Court found no error. The judges emphasised that the colours had a functional role in discount retailing, that the overall impression was governed by each store's own dominant logo and name, and that the consumer compares the complete get-up rather than colours in isolation.

The practical translation is simple. Your colour can be protected, but only to the extent it actually functions as a brand identifier, and only in the context of the whole presentation. A competitor who copies your exact colour scheme and layout in the same market faces genuine exposure. A competitor who uses a similar colour family with its own clearly different logo, name and layout is much harder to stop, whatever your brand guidelines say.

The pitfalls that trip businesses up

Several recurring mistakes explain most of the failed colour claims:

Treating the colour as the whole case: Colour claims live or die on overall impression. If your own brand already has a distinctive word mark or logo, a court will ask why the competitor's different logo and name would not dispel confusion.
Ignoring functional and common colours: Yellow for discount retailing, red for sales, green for environmental claims: colours that carry meaning in the trade are treated as available to everyone. Claiming them as exclusive usually fails.
Amending the description carelessly: The BP litigation was lost partly because changes to the application's description of how the green was applied were held to have substantially affected the identity of the mark. Draft the description correctly at the start; do not rewrite it under pressure later.
Relying on unregistered colour rights: A business name registration, a domain name or even a well-known colour association gives no trade mark rights. Without registration, your only claims are consumer law and passing off, which require proof of reputation and misleading conduct on the facts.
Registering the logo but not the colour use: Conversely, many businesses file a logo in black and white and assume the colour is protected. Under s 70, a mark registered without colour limitation covers all colours, so that is usually true, but only for the logo as filed. A colour used across packaging, signage and uniforms outside the logo is unprotected.

When you need a trade mark lawyer, and what they do

Each stage of the scheme has a point where professional input earns its keep:

Before filing: A clearance search of the register for existing colour and non-traditional marks, plus an assessment of whether the colour is distinctive enough to justify a colour application or whether a word and logo strategy is the better first step. This is also the time to check for unregistered reputations that a register search will not reveal.
Compiling the evidence: Acquired distinctiveness is won on the evidence of use. A lawyer helps structure declarations, gather sales and marketing records, and decide whether consumer survey evidence is warranted, so the material actually addresses what s 41 requires.
Drafting the application: Getting the representation, the concise and accurate description, the colour reference and the goods and services specification right at filing avoids the amendment traps that sank BP.
Responding to examination and oppositions: Adverse reports and opposition proceedings are technical and time-limited. Legal submissions and evidence in response are usually the difference between registration and refusal.
Enforcing or defending: Infringement and misleading conduct proceedings involve significant cost, and a lawyer's early assessment of whether the overall impression argument is winnable often determines whether a dispute settles with a changed shade or escalates to a trial.

The evidence, not the colour, is what you are really buying

The most valuable thing to understand about colour trade marks is that registration does not create distinctiveness; it recognises it. IP Australia and the courts will give you a monopoly over a colour only once you can show the colour already functions as your badge of origin, and they will take that monopoly away, or refuse to enforce it, where the colour is doing functional or descriptive work or where the overall get-up does the distinguishing instead. That is why the case law reads the way it does: Philmac's terracotta fitting insert is registered, while BP's green, Cadbury's purple and Chemist Warehouse's yellow, red and blue are not, at least not as the owners originally hoped.

For a business building a brand, the practical sequence follows directly. Protect your word and logo marks first, decide early whether a colour application is justified by real evidence of consumer recognition, keep the colour description precise, and treat a colour dispute as a dispute about the whole presentation rather than a single shade. A focused review with a trade mark lawyer at the design stage, before packaging is printed or stores are fitted out, is where the leverage is cheapest. The alternative, discovering after launch that your signature colour is considered common to the trade, is a rebrand that no amount of goodwill in the colour itself will pay for.
