Choosing brand colours usually happens backwards. Someone collects a set of palettes they like, the team votes, and the winner becomes the brand. Six months later the palette cannot carry a headline, the accent colour disappears on a photograph, and every new designer quietly adds their own shade to make it work.
The reliable way is to treat colour as a system with roles and jobs. Do that and the palette stops being a preference and becomes a decision, which is exactly what makes it last.
Start with what the brand has to signal
Before any swatch, write the answer to three questions.
- What must this brand feel like? Reassuring, precise, energetic, restrained. Use words from your positioning, not from a colour wheel.
- What does the category already look like? Financial services run blue, wellness runs sage and cream, sport runs high-contrast. Convention is not a trap, but going with it makes recognition harder.
- Do you need to fit in or stand out? Fitting in signals legitimacy in regulated categories. Standing out works when the product genuinely differs. Decide deliberately.
This is why colour follows positioning. A palette chosen from taste can only be defended with taste, and taste changes with the person holding the veto.
Give every colour a role
A working palette is smaller than most people expect, and every colour in it has a job.
- Primary: the one colour that carries recognition. It appears on the logo, the key button, the primary surface. One only.
- Accent: a secondary colour used for attention, links, highlights and states. It must contrast with both the primary and the background.
- Neutrals: the greys, off-whites and deep near-blacks that do the volume work. Most of any layout is neutral, which is why neutrals deserve the most testing.
- Functional colours: success, warning and error. These must be distinguishable from the brand accent, or every form submission becomes ambiguous.
If your palette has five saturated colours and no proper neutral, you do not have a system yet.
Roughly 60 percent neutral dominance, 30 percent secondary, 10 percent primary or accent. It is a sanity check rather than a law, and it instantly reveals palettes that will scream in real layouts.
Contrast is not optional
Colour that looks good in a grid often fails when it has to carry text. Test every combination you intend to use for text against a contrast ratio of at least 4.5:1 for body copy and 3:1 for large headings, and treat anything lower as decoration only.
The other rule is that colour must never be the only signal. A red border with no icon, label or message communicates nothing to a customer who cannot distinguish it. Consistency suffers when a palette is inaccessible, because the first person to hit a readability problem will quietly change the colour, and the next person will change it again.
Print, screen and the real world
A colour exists in four or five technical forms, and the palette should specify each one.
- HEX and RGB for digital: websites, apps, social templates.
- CMYK for process printing: brochures, packaging, stationery.
- Pantone when the colour must be exact on a physical product or a paint finish.
- Monochrome equivalents for the version that has to work in single-colour print, engraving or embroidery.
Expect screens to look more vivid than paper. The goal is a considered relationship between the two, not a match, and documenting both values is what stops the drift that happens when the only file anyone has is a screenshot.
Colour is the fastest way to be recognised and the easiest thing to get subtly wrong. The fix is roles, contrast and a written rule for every medium.
Test the palette before you commit
Run these six checks on any candidate palette.
- Small size. Shrink it to a favicon and a 16-pixel icon. Does the primary still read?
- Greyscale. Convert the palette to grey. If the hierarchy disappears, the palette is carrying too much meaning through hue alone.
- On photography. Place the logo and a headline over a busy photo. Contrast should hold without a heavy overlay.
- In a real screen. Check it on an actual phone at low brightness, not just on the studio monitor.
- In single colour. Print a page in black only. Nothing should break.
- In a chart. Build a six-series graph. If four of the colours blur together, the palette is not finished.
Common mistakes
Too many colours. Every additional accent reduces the recognition value of the others.
Pure black text. Absolute black on a white background is harsh on screens. A near-black neutral reads better and leaves room for the brand ink to stand apart.
Chasing trends. Gradient-heavy or ultra-trendy palettes age fast. A restrained primary plus disciplined neutrals lasts a decade.
Never documenting it. A palette without written roles and values is a mood, and moods do not survive handover. Document it properly, as covered in what a brand guidelines document should contain.
Ignoring the logo’s needs. A colour that works beautifully on a website can fail entirely on a logo lockup. Test both together, and read why a logo is not a brand before you let one colour decision carry the whole identity.
Common questions, answered
How do I choose brand colours?
Start from positioning rather than taste. Decide what the brand needs to signal, check what your category already looks like, then build a palette with defined roles: one primary, one or two accents, and a set of neutrals. Test it on real screens, in print and in greyscale before committing.
What do brand colours mean?
Colour meanings are real but weaker and more context-dependent than most articles suggest. A colour’s meaning comes mainly from the category, the culture and the other colours around it, which is why "blue means trust" is a starting point rather than a rule. Build the palette around your position, then let consistent use create the association.
How many colours should a brand have?
Three to five: a primary colour that carries recognition, one or two accents, and one or two neutrals that do the everyday work of backgrounds and text. Most brands overestimate how many colours they need and underestimate how much contrast they need.
How do I make brand colours accessible?
Check text contrast against a minimum ratio of 4.5:1 for body text and 3:1 for large text, and never use colour alone to carry meaning such as an error state or a link. A palette that fails contrast will be quietly corrected by your own team, which is how consistency breaks.
Why do brand colours look different in print and on screen?
Screens emit light in RGB while print reflects it in CMYK or a Pantone ink, and the two cannot match exactly. The fix is to specify each medium deliberately: HEX and RGB for digital, CMYK for process print, and a Pantone reference when the colour must be exact on a physical product.
What is the most common brand colour mistake?
Choosing colours because they look pleasing in isolation, then discovering the palette cannot produce a readable headline, a clear button or a legible chart. Colour is a system with jobs to do, not a set of swatches, and the fix is to define each colour’s role before you fall in love with it.
Choose colour the way you would choose a material: for what it has to do, not just how it looks in the sample. Define the position, assign the roles, check the contrast, test it on a bad monitor and a black-and-white printer, then write the rules down. A palette that survives those tests will still look right in five years, which is the only real measure of a brand colour.
