Colour is often the first thing people notice about a brand, long before they read a word of copy. A logo, a website header or a piece of packaging can be recognised from across a room simply because of the colours it uses. That makes choosing a palette one of the most important decisions in any identity project, and one of the easiest to get wrong.
In this article we look at how colour works in branding, how to build a palette that is flexible enough for real use, and the common mistakes that make a brand look inconsistent.
Why colour matters in brand identity
Colour does three jobs for a brand. It helps people recognise you, it sets a mood, and it creates structure across everything you publish. When the same colours appear on your website, social media posts, invoices and signage, customers start to connect them with you without thinking about it.
The mood side is more subtle. Colour associations are shaped by culture and context, so there is no universal rule that blue always means trust or that red always means energy. What matters is how your palette fits your sector, your audience and the personality you want to project. A law firm and a children's toy shop can both use yellow, but they will use it very differently.
The basics of colour theory
A little theory goes a long way when you build a palette. The colour wheel is the usual starting point. Complementary colours sit opposite each other and create strong contrast, which is useful for calls to action. Analogous colours sit next to each other and feel calm and harmonious. A triadic scheme uses three evenly spaced colours and can feel lively if one of them is allowed to lead.
Beyond hue, think about value (how light or dark a colour is) and saturation (how intense it is). Many palettes that look good on a mood board fail in practice because every colour has the same strength. Varying lightness and intensity gives you room to create hierarchy, so the most important element on a page really stands out.
Building a practical palette
A useful brand palette usually has a clear structure:
- Primary colour. The colour most closely tied to the brand, used for the logo and key moments.
- Secondary colours. One to three supporting colours that add variety without competing with the primary.
- Neutrals. Greys, off-whites or dark tones for text, backgrounds and dividers. These do most of the work on a typical page.
- Functional colours. Colours reserved for states such as success, warning and error in digital products.
Define each colour in the formats you will actually need: HEX and RGB for screens, and CMYK or a Pantone reference for print. Colours can shift noticeably between screen and paper, so it is worth testing printed samples before you commit.
Colour, accessibility and the web
A palette has to work for everyone who reads your content. Text needs enough contrast against its background to stay legible, and important information should never depend on colour alone. Someone with colour vision deficiency may not see the difference between a red and a green status label, so add icons, labels or patterns as well.
Checking contrast early saves a lot of rework later. If your favourite brand colour is too light for body text, keep it for larger headings, buttons with dark text or decorative elements, and choose a darker shade for small text. Our web design work always includes these checks before a palette goes live.
Common mistakes to avoid
The most frequent problem we see is a palette that grows without a plan. A new campaign introduces a new colour, a different team picks a slightly different shade, and within a year the brand feels scattered. A simple style guide that lists approved colours and shows how to use them prevents most of this.
Other pitfalls include choosing colours purely on trend, using too many accent colours at once, and forgetting how the palette looks in dark mode or on low-quality screens.
Bringing it together
A good brand palette is not just attractive. It is consistent, accessible and easy for anyone on your team to apply. Start with a clear primary colour, support it with a small set of secondary and neutral tones, and test everything in real situations.
