Logo, colours and typography: building your company's visual identity
What visual identity is and why it matters
Visual identity is a set of graphic elements through which a company communicates externally — logo, colour palette, typography, icons, photographic style and rules for their use. It's not the same as a brand. A brand is the overall impression and relationship a customer builds with the company. Visual identity is the tool that purposefully shapes this impression.
A well-designed visual identity helps in three areas: it makes recognition easier, creates a professional impression that builds trust, and differentiates the company from the competition. Conversely, inconsistent visuals — a different logo on the website and invoices, various shades of the same colour, randomly chosen fonts — appear amateurish and make it harder for customers to remember the brand.
Logo: the cornerstone of identity
The logo is the most visible element of visual identity. It works across all channels — from business cards to websites and social media — so it must meet several practical criteria:
Simplicity — the logo must be readable at a small size (favicon, profile photo) and in a large format (billboard). A too detailed logo falls apart at smaller sizes.
Originality — distinguish yourself from the competition. Generic logos don't stick in customers' minds.
Timelessness — design trends change. A logo should last at least 5–10 years without needing a redesign.
Functionality in one colour — a quality logo must also work in black and white. If it relies solely on colour gradients or light effects, it will fail when printing invoices or using a stamp.
Types of logos
Wordmark — a logo consisting of the stylised name of the company (e.g., Google, Coca-Cola). Suitable for companies with short, distinctive names.
Lettermark — a monogram of initials (HBO, IBM). Works for companies with long names.
Symbol/pictogram — only a graphic symbol without text (Apple, Nike). Requires strong recognisability, often unsuitable for new companies.
Combination mark — symbol + text (Adidas, Lacoste). The most flexible option — the symbol can be used alone as an avatar on social media, while the text ensures readability.
Emblem — text inside a symbol (Starbucks, Harley-Davidson). Appears traditional, but harder to scale to small sizes.
For most new companies, a combination mark is the safest choice — it offers the greatest flexibility across various uses.
Company colours: more than just a matter of taste
Colours carry emotions and associations. Choosing a colour palette is not just an aesthetic decision — colours affect how the customer perceives the company. Blue usually appears trustworthy and professional, which is why banks and tech companies choose it. Green evokes nature, health, and growth. Red conveys energy and urgency. Black suggests luxury and seriousness.
Structure of the colour palette
The recommended structure for a functional palette is as follows:
1 primary colour — the dominant brand colour, most associated with the logo
1–2 secondary colours — complement the primary, used for accents and differentiation
2–3 neutral colours — shades of grey, white, and cream for backgrounds and texts
1 highlight colour — for buttons, calls to action, and important elements
Define each colour exactl — with a HEX code for the web (e.g., #2E5BFF), CMYK for print, and RGB for digital use. Without exact values, the colour will slightly differ in each material.
Accessibility and contrast
An important but often overlooked aspect: colour combinations must be readable. Light grey text on a white background may look elegant, but a large part of users won't be able to read it. The contrast between text and background should meet the WCAG (Web Content Accessibility Guidelines) standard — at least a ratio of 4.5:1 for normal text. Online checking can be done by free tools like the WebAIM Contrast Checker.
Typography: the silent power of the brand
Typography influences how everything you write feels — from the website to emails and invoices. The choice of a font communicates the nature of the company just as much as colours do.
Basic font categorisation
Serif — fonts with decorative serifs (Times New Roman, Georgia, Playfair Display). They feel traditional, trustworthy, formal. Suitable for law firms, finance, and luxury brands.
Sans-serif — modern, clean fonts (Helvetica, Arial, Inter). They feel modern, clear, and accessible. A standard for tech companies and digital products.
Script — reminiscent of handwriting. Use cautiously, often illegible in regular text.
Display — bold, decorative fonts for headings. Do not use for longer texts.
The two-font rule
For most companies, two fonts suffice: one for headings, another for regular text. A maximum of three. More fonts look chaotic and undermine consistency.
A proven combination is a contrasting pair — serif heading + sans-serif text, or vice versa. Equally effective is a combination of the same family in different weights (e.g., Inter Bold for headings + Inter Regular for text).
Brand manual: keeping consistency
Visual identity only works if used consistently. A key tool is a brand manual (brand guidelines) — a document that describes how individual elements should be used. It should include at least:
logo in various versions (colour, monochrome, on light and dark backgrounds)
logo's safe zone and minimum size
things never to do with the logo (distortion, wrong colours, unsuitable backgrounds)
colour palette with HEX, RGB, and CMYK values
typography — fonts, weights, and sizes for different uses
examples of use on business cards, documents, and social networks
Example:
A company has a blue logo. Without a manual, one designer uses the shade #1E40AF, another #3B82F6, and on social media appears #2563EB. All three are 'blue', but together they seem like each material came from a different company. With a manual, only the defined shade is used, and the brand is instantly recognisable.
Even a simple 5-10 page manual significantly improves how consistently visuals will appear. It's especially important when identity is handled by different people — an internal team, an external designer, or a marketing agency.
One of the places where a consistent visual identity is most evident is in everyday company documents. An invoice is not just an accounting document — it's another point of contact with a customer and an extension of your brand.
