How to Choose Brand Colours for Your Irish Business
Choose your brand colours in this order: decide who you serve and how you want to be seen, pick one main colour that fits, add one accent for buttons and highlights, then use near-black for text and a light neutral for backgrounds. Test the result on your website for contrast and readability before you commit. That gives you a palette you can use on a website, van, invoice and business card without it looking different each time.
Most new business owners get stuck because they treat colour as a matter of taste. It is a working decision. Your colours have to be readable, recognisable and easy to reproduce. This guide walks through the process, with examples from Irish institutions and the accessibility rules that apply to any website.
TL;DR
- Start with your audience and your positioning, not with your favourite colour.
- Colour psychology is a loose guide, not a formula. Context, contrast and consistency matter more than the “meaning” of a hue.
- Keep it small: one main colour, one accent, near-black for text and a light neutral. Add a third colour later if you need it.
- On a website, aim for WCAG AA contrast: 4.5:1 for normal text and 3:1 for large text and buttons.
- Write your colours down as HEX, RGB and CMYK values so every sign, leaflet and web page matches.

Start with the business, not the colour wheel
Before you open a palette tool, answer three questions in plain words:
- Who are you selling to? A plumber in Cork serving homeowners has a different audience from a B2B bookkeeper in Dublin 2.
- What do they need to feel when they land on your page? Reassured, energised, calm, confident that you are established?
- Who else do they see? If every competitor in your trade uses the same dark blue and orange, you may want to stand apart, or you may want to look like a safe, familiar choice. Both are valid, but it should be a decision.
Write down three to five words for your brand: for example “reliable, local, straightforward”. Those words become your brief. A colour is then right because it supports them, not because it looks nice on a screen.
This matters because colour does not create a brand on its own. It supports a brand that already has a clear idea behind it. Consistent, repeated use over time is what makes a colour feel like yours.
What colour psychology can and cannot tell you
Search for brand colours and you will find endless charts: blue means trust, red means urgency, green means growth. They are tidy and mostly overconfident.
An academic review in the Annual Review of Psychology describes research on colour psychology as still at a nascent stage, with more work needed on the conditions under which colour effects occur and whether they hold up in real-world settings. A later systematic review covering 128 years of colour and emotion research points out that most colour and emotion links were tested as abstract associations, so it is still unclear how far they carry over to specific, real situations.
What does that mean for you?
- Use associations as a starting point. Green often reads as natural or fresh, dark blue as steady, warm tones as friendly. Treat these as hypotheses, not guarantees.
- Look at your own sector. A funeral director, a children’s entertainer and a solicitor each work with different expectations, whatever any chart says.
- Think about culture. Colours carry different meanings in different places. If you sell to customers abroad, check that your choice does not send an unintended message.
- Ask real people. Show two or three options to a handful of customers and see which one they trust, remember or find easiest to read. That tells you more than a list of meanings.
The practical takeaway: pick colours that fit your brand words, stand out from your closest competitors and stay readable. Let the rest follow from consistent use.
Build a palette of roles, not a rainbow
A good small business palette is a set of jobs. Each colour has a role and keeps it everywhere.
| Role | What it does | Where it appears |
|---|---|---|
| Main colour | Carries your identity | Logo, headings, header or footer bands |
| Accent colour | Draws the eye to action | Buttons, links, key highlights |
| Near-black | Keeps text easy to read | Body copy, forms, invoices |
| Light neutral | Gives space to breathe | Page backgrounds, cards, panels |
For most new businesses, that is enough. You can add a third colour later if a clear need appears, such as separating service lines or marking offers. Starting with a restrained palette makes every later design decision easier, and it stops your site looking busy.
How to pick the main colour
Take your three to five brand words and your closest competitors. Collect a handful of candidates, then ask:
- Does it suit the feeling I want people to have?
- Does it look different enough from the two or three businesses customers will compare me with?
- Will it work on white and on a dark background?
- Will it look right on a van, a sign, a polo shirt and a phone screen?
If you already have a logo, the main colour is probably decided. Build the rest of the palette around it.
How to pick the accent
The accent is the colour people click. It should contrast clearly with both your main colour and your background. Many businesses choose a warm accent against a cool main colour, or the other way round, because the difference makes buttons obvious. Use it sparingly: if everything is highlighted, nothing is.
Handling shades and variations
You can create lighter and darker versions of your main colour for backgrounds, hover states and borders. Keep them as variations of the same colour rather than new colours. It keeps the look unified without adding to the palette you have to manage.
What Irish institutions can teach a small business
Large organisations publish brand guidelines, and the colour rules are surprisingly sensible for any size of business.
The Technological University of the Shannon’s brand guidelines use three primary colours most often and allow a single secondary colour alongside them. They call for high-contrast combinations and say to avoid multiple secondary colours and low-contrast pairings. That is a university with many faculties and audiences, and it still keeps its palette tight.
Trinity College Dublin’s secondary colour guidance says secondary colours should support the primary palette rather than dominate it, and that tints should not be used for text, buttons or interactive elements where WCAG AA contrast is required.
Three lessons to borrow:
- Limit the supporting colours. Fewer, used consistently, beats many used occasionally.
- Let the primary palette lead. Supporting colours should never compete with it.
- Do not use pale tints for anything people must read or click. Pale tints are fine for backgrounds, but not for text or buttons.
A few sample combinations for local businesses
These are starting points, not rules. Adjust them to your own brand words.
- Tradesperson (electrician, plumber, roofer): deep navy main colour, bright orange or amber accent, near-black text, off-white background. Reads as dependable and is easy to spot on a van.
- Health and wellbeing (physio, therapist): muted teal or sage main colour, warm coral accent, charcoal text, soft cream background. Calm but not clinical.
- Professional services (accountant, solicitor): dark green or charcoal blue main colour, a single gold or bright blue accent, near-black text, light grey panels. Serious without feeling cold.
- Food and hospitality: a rich main colour that matches the food or setting, a contrasting accent for booking buttons, and a neutral that photographs well.
Whichever you choose, check the actual shades for contrast, which brings us to your website.
Making brand colours work on a website
A colour that looks lovely in a logo can fail badly on a web page. Three things decide whether your palette works on screen: contrast, consistency and not relying on colour alone.
Contrast
The Web Content Accessibility Guidelines (WCAG) set contrast levels for readability. Trinity College Dublin summarises the AA thresholds: at least 4.5:1 for normal text, 3:1 for large text, and 3:1 for non-text elements such as buttons, icons and interface borders. Free contrast checkers let you paste two HEX codes and see the ratio instantly.
That has direct consequences for your palette:
- A light yellow or pale green accent on a white background will usually fail. Choose a darker version for buttons and text.
- White text on your main colour needs checking too. Many mid-tone colours look fine but miss 4.5:1.
- Grey text on a light grey panel is one of the commonest failures on small business sites.
Do not rely on colour alone
The W3C’s guidance for visual designers says that under WCAG 2.1, colour should not be the only way to convey information, indicate selection or show the presence of errors. In practice: a form error needs a message and an icon as well as a red outline. A link inside body text should be underlined or otherwise marked, not just coloured.
Use the accent for one job
On a service business site, your accent colour should mean “do something”: call, request a quote, send an enquiry. If it also appears on decorative elements, headings and icons, buttons lose their pull. Keep one clear action colour and use it for your main call to action on every page. The same principle applies to a single-purpose page. Our guide on homepage versus landing page explains why one campaign should have one call to action, and a consistent action colour supports that.
Where each colour goes on a typical small business page
- Header: logo, main colour or white background, accent only on the contact button.
- Hero section: a light or dark neutral background, headline in near-black or white, one accent button.
- Service sections: alternate white and light neutral panels, headings in main colour.
- Enquiry form: white or light panel, clear labels in near-black, accent on the submit button.
- Footer: main colour or near-black background with light text, checked for contrast.
Keep colours consistent beyond the website
Your website is one place customers meet your brand. They also meet it on a van, a business card, an invoice, a social profile and a Google Business Profile. If the blue is slightly different on each, you look less established than you are.
Record each colour in the formats you will need:
- HEX for websites and most online tools.
- RGB for screens and presentations.
- CMYK for print. Bright screen colours can reproduce more dully on paper, so ask for a proof of anything that matters, such as signage or vehicle graphics.
- A Pantone reference, optional, if you need to match a colour exactly across suppliers.
Also check that your logo works in one colour, in black and white, and on both light and dark backgrounds. You will need those versions for stamps, embroidered workwear and fax-style black and white copies that still turn up in some trades.
A one-page “brand sheet” with your colours, their values, the role of each and your logo versions is enough. Hand it to any sign writer, printer or web designer and the result will match.
If you are planning a refresh of an existing brand, our rebrand website plan shows how to roll new colours out across a site without losing what customers already recognise.
A step-by-step process you can finish in an afternoon
- Write your brand words. Three to five, based on your customers and how you want to be seen.
- Look at the competition. Note the dominant colours of the three or four businesses your customers will compare you with.
- Choose two or three main colour candidates. Make sure each suits your words and looks distinct from the competition.
- Pick an accent for each candidate. It should contrast clearly with the main colour and the background.
- Set text and background colours. Near-black text, light neutral background.
- Run contrast checks. Text on background, text on buttons, button against background. Aim for 4.5:1 for normal text and 3:1 for large text and buttons.
- Mock it up. Put the palette on a rough homepage, a business card and a van or sign. Look at it on a phone in daylight.
- Ask five people. Customers, friends who run businesses, anyone who fits your audience. Which feels most like you? Which is easiest to read?
- Lock it in. Write down HEX, RGB and CMYK values and the role of each colour.
Then leave it alone. A palette that you keep for years builds recognition far better than one you refine every season.
Common mistakes to avoid
- Choosing for your own taste only. You are not the customer.
- Too many colours. Beyond a main colour, accent and neutrals, each addition makes the brand harder to apply.
- Low-contrast text. Fashionable pale grey on white looks stylish and is hard to read, especially on a phone outdoors.
- Copying a big brand. Borrowing a well-known colour combination can confuse customers. Take the principle, not the exact palette.
- Different colours in different places. A logo file with one blue, a website with another, and a van with a third.
- Deciding before you know your website needs. If you plan a site with enquiry forms, WhatsApp buttons and service pages, think about how many interactive elements need an accent colour and how they sit on your chosen background.
Our perspective
We build websites for new and small Irish businesses, and colour is one of the first decisions that slows owners down. They worry about picking the “wrong” one. In our experience the wrong choice is rarely a bad hue. It is a colour that is hard to read, applied differently on every page, or chosen with no thought for who is looking.
That is why we keep the process simple. We start with what you do, who you serve and what they need to feel. Then we choose a small palette, check it for contrast and use it the same way everywhere. The main colour carries the brand, the accent carries the action, and plain text and neutral backgrounds keep the page readable on a phone.
We would rather you have a modest, consistent palette on a fast, clear website than a clever one that looks different on every page. If you need help, we can set up your colours alongside a logo and starter branding, and then build them into your site, so you are not trying to match values yourself. You deal directly with the person building your site, and we keep the jargon out of it.

FAQ
How many colours should a small business brand have?
Start with one main colour, one accent, near-black for text and a light neutral for backgrounds. That is enough for a website, signage and stationery. Large Irish institutions keep it tight too: the TUS guidelines use three primary colours with at most one secondary. Add more only when you have a specific need.
Does colour psychology really work for brands?
It gives you useful starting points, but not guarantees. Academic reviews describe the field as still developing, and effects depend on context. Choose colours that fit your brand words and audience, then check them for readability and consistency.
What colours work best for a website?
There is no single best colour. What works is contrast and clarity: dark text on a light background, a main colour that reflects your brand and an accent that makes buttons obvious. Check text at 4.5:1 for normal size and 3:1 for large text and buttons, as set out in the WCAG AA thresholds.
Should I choose my colours before or after my logo?
Choose them together, or let the logo lead. Your logo’s main colour usually becomes your brand’s main colour. If you are starting from scratch, decide the palette first, then check that the logo works in one colour and on light and dark backgrounds.
