Colour Psychology: How to Choose Your Brand Colours

29 June 2026·4 min read

Quick answer: Your brand colours should be chosen by the feeling you want customers to have and the industry expectations you're either meeting or deliberately breaking — not by what colour you personally like most. Pick one dominant colour, one supporting colour, and one accent, and test them against your competitors before locking anything in. 💖

"What colour should my logo be?" is one of the most common questions small business owners ask, and it's usually answered with a personal favourite rather than a strategic decision. Blue because it's calming. Pink because it's pretty. Black because it looks premium. All true in isolation, and all missing the actual point — colour is a shortcut your brain uses to make snap judgements about trust, price, and personality before a single word is read.

Colour psychology isn't an exact science, but the patterns are consistent enough to build a real decision around. Here's how to actually choose, instead of guessing.

What most people get wrong

Picking a favourite colour instead of a strategic one. Your personal taste and your customer's expectations are two different things.
Ignoring what the industry already signals. Green in health and finance reads as "growth" or "money." Breaking that convention can work, but only if you know you're doing it.
Using too many colours. More than three core colours and your brand starts looking like it doesn't have a system at all.
Copying a competitor's palette. If you look identical to the market leader, customers will default to the one they already trust.
Choosing colours before defining the brand's personality. Colour should follow strategy, not lead it — decide who you're speaking to first.

The 3-colour palette formula

This is the exact framework we run clients through before touching a single hex code.

Copy-paste palette-building checklist:

Pick three words that describe how you want customers to feel (e.g. "trustworthy, warm, modern"). Every colour choice gets tested against these words.
Choose your dominant colour — the one that carries 60% of your visual identity, usually tied to your core emotion (trust = blue, energy = orange/red, calm = green or soft blue).
Choose your supporting colour — roughly 30% of use, often a neutral (cream, charcoal, soft grey) that lets the dominant colour breathe.
Choose one accent colour — the remaining 10%, used sparingly for calls to action and highlights so it keeps its impact.
Check it against three competitors. If your palette is nearly identical to theirs, adjust the shade or swap the accent until you're visibly distinct.

Real examples

Law firm: A firm wanting to signal established trust without feeling old-fashioned leans on a deep navy as the dominant colour (authority, stability) with warm cream as the supporting tone to soften it, and a single muted gold accent for calls to action — trustworthy but not stiff.

Psychology or allied health clinic: Rather than clinical white and blue, the practice chooses a dusty sage green as dominant (calm, growth, non-clinical) with soft terracotta as an accent — warm enough to feel human, still clearly a health brand.

Financial planner: Deliberately avoiding the expected "money green," the planner uses a deep teal as dominant to feel modern and calm rather than corporate, paired with charcoal and a soft gold accent — recognisably finance-adjacent without blending into every bank logo on the market.

💡 Heads up: Colour meaning shifts by culture and context, and it's not a universal formula — red means danger in one context and celebration in another. Treat colour psychology as a strong starting point, not gospel, and always sense-check your final palette against how your actual customers respond, not just theory.

It's also worth being honest that colour alone won't fix a weak brand. A perfectly chosen palette on a confusing logo, inconsistent fonts, and a website that doesn't explain what you do will still underperform. Colour is one layer of a system — powerful, but not a substitute for clarity everywhere else.

Testing before you commit

Once you've got a shortlist, don't just stare at it on a screen. Mock the palette up on a business card, a social tile, and a website header — colours read completely differently at different scales and in different contexts. If it still feels right across all three, you've probably got the right palette.

Frequently asked questions

How many brand colours should I actually use?

Three is the sweet spot: one dominant, one supporting neutral, and one accent. More than that and your visual identity starts to feel unsystematic.

Should I follow industry colour conventions or break them?

Know the convention first, then decide deliberately. Following it (blue for trust in finance, green for health) is safe; breaking it can make you stand out, but only works if the rest of your brand backs up the choice.

Does colour psychology actually affect sales?

It affects first impressions and perceived trust, which influence behaviour, but it's one factor among many — messaging, pricing, and reputation still do most of the heavy lifting.

What if I already have brand colours I don't love?

You don't need a full rebrand to fix it. Often adjusting the shade or ratio of an existing colour (a warmer navy, a softer green) solves the issue without starting from scratch.
