Brand identity is more than a logo: the system, the guidelines and the trade mark

You have a logo, and you like it. But the sales deck uses one navy, the trade show stand uses another typeface, and the LinkedIn page shows a third version with the edges cropped off. Finance puts the old logo on invoices; the new starter designs their own email signature. Nobody is doing it on purpose. Nobody knows what the right version is.

This article covers what it takes to turn a single logo file into a system people can use every day, plus the legal side: registering the trade mark. Commissioning a new identity? You will know what to ask for. Tidying up an existing one? You will know where to start.

Strategy first, visual identity second

Brand strategy answers a plain question: who you serve, what you promise them and why they should believe you. Visual identity is how that answer looks: logo, colour, type, photography, icons. You can design an identity without a strategy. You just can't explain why any decision was made.

The pattern we see most often: in the design meeting everyone defends their own taste, and with no criteria on the table the debate never ends. Two or three sentences agreed in advance (say, “We are a calm, dependable supplier to heavy industry, chosen for our engineering depth”) cut that meeting in half. Does the logo proposal fit the sentence? That becomes the question.

You don't need a thick strategy document. Written answers to these questions, signed off by the leadership team, are enough for most organisations:

• Who are we for, and which of their problems do we solve?
• When customers choose us over a competitor, what reason do they give? Ask them rather than guess.
• Which three adjectives describe us, and which three must never describe us?
• Which markets and languages do we want to be in five years from now?

The last question has a practical side: how your name reads in other languages, whether something similar is registered in your target markets, whether the domain is free. Check at the start, not at the end.

Not a logo, a logo system

A single logo file looks good in a single situation. In real life your logo will sit on a building sign, in a tiny browser tab and on a one-colour courier label. What you should receive is a family of versions that work together.

Primary logo and lockups

The primary logo, usually symbol and wordmark together, is the most recognisable version. Alongside it you need at least a horizontal lockup for wide, shallow spaces (website header, email signature, letterhead) and a stacked version for narrow, tall ones (pull-up banners, social posts, the side of a box). Improvised later, the proportions drift; they should be drawn on the same grid from the start.

Two rules are written for every version: clear space (the area nothing else may enter, usually defined by a unit taken from the logo itself, such as the height of one letter) and minimum size, in millimetres for print and pixels for screen.

Symbol, favicon and small sizes

If part of your logo can stand alone without the name, that is your symbol. Favicons, app icons, social profile pictures and rubber stamps are solved with it. Most platforms crop profile pictures to a circle, so check that the symbol still sits comfortably inside one.

At small sizes thin lines disappear and letters merge, so good systems include a simplified drawing for very small uses. Test it on a phone at real size, not on a projector.

One colour, reversed and misuse

The one-colour version, the reversed version (white on dark) and a version that survives single-colour print all belong to the system. When engraving, embossing or a one-colour T-shirt comes along, turning the colour logo grey almost always looks washed out.

The guidelines should also show what not to do: stretching the logo, adding shadows, changing its colours, placing it over a busy photo. That page isn't there to scold anyone. It stops well-meant mistakes before they happen.

Files and ownership

At handover, ask for a vector master (Illustrator or Figma), PDF or EPS for print, SVG and transparent PNG for screen, and a favicon set. Name files so people understand them: “logo_horizontal_reversed.svg” works, “final_FINAL_v7” does not.

Then there is ownership. Paying an invoice does not by itself make you the owner of the design. Under UK copyright law, an assignment only takes effect if it is in writing and signed by, or on behalf of, the person assigning it. Your contract should state which rights pass to you; have your legal adviser check that the paperwork you hold actually does.

A colour system: on screen, in print and for everyone

“Our brand colour is navy” is not a colour system. The same navy looks different on coated paper, uncoated paper, a phone and a vehicle wrap. A colour system gives a code for each medium and says where, and how much, each colour is used.

A code for every medium

• HEX and RGB values are for screens: website, social media, presentations, apps.
• CMYK is for four-colour print. Coated and uncoated stock may need different values; decide with your printer, on a proof.
• Spot colours such as Pantone are worth specifying for packaging and merchandise.
• For signage, vehicles and shopfronts, specify a RAL reference or the paint manufacturer's code.

The codes should not be automatic conversions of one another; a spot colour converted by software usually looks dull on screen. Pick the screen colour on a screen and the print colour on a proof, then check that the two sit close enough.

Accessible contrast

A colour can be beautiful and still fail if the text on it can't be read. At level AA, the Web Content Accessibility Guidelines (WCAG) require a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Interface elements that carry meaning, such as button outlines, form field borders and icons, have a 3:1 threshold too. White on orange and grey on light grey fail this test regularly.

If your brand colour misses the mark, you don't have to drop it. Use it on large surfaces and decorative elements, and define a darker variant for text and buttons. If you sell to consumers in the EU, the European Accessibility Act, in force since June 2025, puts this on your agenda anyway; in the UK, service providers already have duties under the Equality Act 2010.

Roles and proportions

In a good palette every colour has a job: a primary, supporting colours, an accent for buttons and key links, neutrals, and system colours for errors, warnings and success. Splash the accent everywhere and nothing stands out. If your brand colour is red, separate it from your error colour from day one.

Typography: choosing a typeface and reading the licence

Type is the most visible part of an identity. You see the logo once on a page; you see the type on every line. Two families are enough for most organisations: one with character for headings and one that stays comfortable over long passages. Sometimes a single large family with several weights and widths does both.

Check the character set before you fall in love. If you trade across Europe, set a line containing £, €, ß, ü, ø and ł; plenty of display faces lack some of them or have glyphs that look bolted on.

Licensing: the clause everyone skips

Typefaces are software, and they come with a licence. Commercial fonts are usually licensed by use: desktop, web (often capped by monthly page views) and app. A font licensed on the designer's computer is not automatically licensed for your website or for the forty laptops in your office.

Fonts on Google Fonts are released under open-source licences, mostly the SIL Open Font License, and Google's own FAQ says they can be used commercially. That doesn't make them a poor choice. It just takes more work to look distinctive, because countless sites use the same families.

For every typeface, the guidelines should record the name, weights in use, licence type, licence holder and a fallback. Without a named fallback for Office documents and email, such as Arial or Calibri, everyone picks their own.

Visual language and tone of voice

Two organisations with the same logo and colours can feel completely different. The difference comes from visual language and the way they speak. Leave these without rules and every campaign pulls the identity a little further off course.

Photography

A photography guide answers a few questions. Real employees or models? Natural light or studio? The product alone or in use? For manufacturers, the strongest images are often the real plant and the real team; a smiling stock model in a hard hat tells visitors nothing.

Icons and illustration

Consistent icons come down to a few technical decisions: outline or filled, stroke weight, corner radius, grid. Put icons from three libraries side by side and even the least observant reader notices. Illustration style should be described with examples too.

Tone of voice and writing rules

Voice is the brand's fixed character; tone adjusts to the situation. In an error message, a product launch and a condolence note, the same brand uses different tones but always sounds like the same person. Set out three or four voice principles, each with “we write this, not that” examples.

Writing rules are drier, yet people use them most: “we” or the company name, Oxford comma or not, UK or US spelling, date formats, capitals in headings, banned words. One page of this removes most everyday inconsistency.

Brand guidelines and digital applications

Brand guidelines keep the identity in shape after its designers have left the room. Their readers are printers, sign makers, the social media team, the new marketing hire and your distributors, so they need to be easy to find. A web page that gets updated, or a shared folder with download links, usually beats one heavy PDF.

The table shows what you should have at the end of an identity project and what most often goes missing.

Where the identity is used every day

Identity projects are still presented with a business card and letterhead. The places your identity is seen most look different:

• On the website, define colours, type scales, spacing and components as design tokens, and the site and guidelines won't drift apart.
• Social media needs a profile symbol, cover images and post templates. Platform dimensions change often, so editable templates age better than fixed sizes in a PDF.
• Email signatures have to survive clients that block images by default; a signature made of one image is the worst option. UK limited companies must also show details such as registered number and registered office on business correspondence, email included, so build them into the template.
• Presentation templates are what the sales team uses most. Provide PowerPoint or Google Slides files with masters set up.
• Your Google Business Profile, Amazon storefront, LinkedIn page and favicon are usually the last things updated after a rebrand.
• Proposals, invoices and the logo in your accounting software count too. That logo often stays unchanged for years.

Common rebrand mistakes

A rebrand is the riskiest kind of identity work: you already have something people recognise, and you are changing it. The mistakes we see most:

• Prescribing before diagnosing. “Our logo looks dated” is not a diagnosis. Is the real problem that people don't understand what you do, that you attract the wrong customers, or two cultures after a merger? The answer changes the job.
• Throwing recognition away. Find out first which element customers know you by. Sometimes the right move is to keep it and renew everything around it.
• Leaving the trade mark search until last. Discovering in the final week that your new name resembles someone else's registered mark is expensive and demoralising.
• Treating launch day as the day everything changes. Signs, vehicles and packaging stock don't change overnight. Plan the order of replacement and how long old material may be used.
• Treating a domain change as a design task. Redirecting old URLs is a project in its own right; our article on keeping your SEO through a site migration covers it.
• Shelving the guidelines after launch and telling staff at the last minute. Your team needs to understand the new identity before customers see it.

Trade mark registration: protecting the identity in law

Having a logo designed doesn't stop others using something similar in your field. Registration does. Where you file depends on where you trade:

• In the UK, applications go to the Intellectual Property Office (UKIPO). Accepted applications are published in the Trade Marks Journal, and third parties have two months to oppose, extendable to three with a notice of threatened opposition. A UK registration lasts ten years and can be renewed every ten years. Since 1 January 2021, EU trade marks no longer cover the UK.
• One application to the EU Intellectual Property Office (EUIPO) covers every EU member state. The opposition period is three months from publication, and registration lasts ten years from the filing date, renewable indefinitely.
• The USPTO expects use in commerce or a bona fide intention to use the mark. After registration, a declaration of use is due between the fifth and sixth year, then renewal between the ninth and tenth year and every ten years after. Miss these filings and the registration is cancelled.

Wherever you file, you choose classes of goods and services under the Nice Classification, and protection only applies in those classes; think about where the business will be in a few years. For several countries at once, WIPO's Madrid System lets you extend a home application or registration through one international application.

One detail people miss: a domain name, a registered company name and a trade mark are three different things. Owning the domain or the name at Companies House does not mean the name is protected as a trade mark.

Where to start

If you already have a logo and inconsistent use, try this sequence before commissioning a new identity:

1. Take an inventory of the logos, colours and fonts in use today on the website, presentations, social media, signage and invoices. Put screenshots on one board; the picture speaks for itself.
2. Gather source files and rights: who holds the vector logo, whose name are the font licences in, does the contract assign copyright to you?
3. Write your strategy sentences, get leadership sign-off and weigh every later design decision against them.
4. Check your trade mark position: classes covered, renewal dates, similar marks in target markets.
5. Complete the logo system and palette: missing versions, screen and print codes, a contrast table.
6. Build the three most-used templates now: presentation, email signature, social post. Templates change behaviour faster than guidelines.
7. Put the guidelines where everyone can reach them, and make one person responsible for keeping them current.

At AYTE Digital we handle identity work together with the design of the website, presentations and social templates. If you want to tidy up your current identity or fill in the rules it lacks for digital use, we can start with the inventory and work out with you which pieces you actually need.
