Colour psychology in packaging: how to choose colours that work

Colour is usually the first thing a shopper notices about a package, often before they read a word. It signals the category, the flavour or variant, the price point and the brand's personality. It is also surrounded by myths: lists that claim red always means excitement or blue always means trust. This guide explains how colour really works on packaging, why context matters more than fixed meanings, and how to choose, apply and test a palette that helps your product sell.

Why colour matters so much on packaging

Shoppers scan shelves and screens quickly. Colour is processed faster than text or detailed imagery, so it does several jobs at once:

• Finding: customers often look for a colour before they look for a name. Distinctive colours make products easier to find again.
• Categorising: colour signals what kind of product it is.
• Differentiating: colour separates variants within a range.
• Positioning: colour suggests price, quality and personality.
• Emotion: colour can create a mood that supports the brand.

The problem with colour meaning lists

You will often see lists of colour meanings: red for energy, green for nature, black for luxury. They contain some truth, but they are not rules.

Colour associations depend on:

• Culture: colours carry different associations in different countries and communities.
• Category: a colour can mean different things in different categories. Green may suggest natural ingredients in skincare, mint flavour in confectionery, or a particular style in beer.
• Shade and saturation: a bright lime green and a deep forest green send very different signals.
• Combinations: colours are rarely seen alone; their combinations and proportions matter.
• Context: the same colour can stand out on one shelf and disappear on another.
• Brand history: some brands own colours so strongly that the association is with the brand, not the colour itself.

Use colour associations as starting points for exploration, not as answers.

Category colour codes

Many categories have colour codes: conventions customers rely on to navigate. For example, certain colours may commonly signal particular flavours, fat content, strengths or product types within a category. These codes vary by market and change over time.

Category codes are useful because:

• they help customers find what they want quickly
• breaking them can confuse customers

But following them too closely means looking like everyone else.

A practical approach:

1. Map the category: photograph the shelf or screen, and note dominant colours and codes.
2. Identify must-follow codes: for example, variant colours that customers rely on.
3. Find space: look for a colour or combination that no competitor owns.
4. Use codes in secondary elements: follow variant codes in accent colours while keeping a distinctive brand colour.

Owning a colour

Some of the most recognisable brands are known for a single colour. Owning a colour has big advantages:

• customers find you faster
• the colour becomes part of your brand identity across packaging, marketing and digital
• competitors find it harder to copy you without looking like imitations

To own a colour:

• choose one that is distinctive in your category
• use it consistently across every product and touchpoint
• use it in large enough areas to be noticed
• protect it from dilution by too many other colours

Colour and price perception

Colour influences how expensive a product looks, but not through simple rules. Premium can be expressed through:

• restraint: fewer colours and more empty space
• depth: rich, deep shades rather than bright primaries
• contrast: black and white, or dark backgrounds with metallic accents
• material effects: foil, metallic inks and textured papers

Value can be expressed through bright, saturated colours and busy layouts, although many value brands now use clean, simple palettes. The right approach depends on the category and where you want to sit within it.

Building a packaging palette

A typical packaging palette includes:

• a primary brand colour, used consistently across the range
• secondary colours that support the brand
• variant colours that separate products
• neutral colours for text and backgrounds

Proportions

Decide how much of the pack each colour covers. A strong brand colour usually needs to cover a significant area to be noticed. Accent colours work best in small amounts.

Variant colour systems

For ranges, assign a colour to each variant. Make sure:

• colours are distinct enough to tell apart quickly
• the system scales as you add products
• colours do not clash with the brand colour
• variants are also identified by text, not colour alone, for accessibility

Colour and accessibility

Around 1 in 12 men and 1 in 200 women have some form of colour vision deficiency. Many people also have reduced vision. To make colour work for everyone:

• Do not rely on colour alone to communicate variants or important information; add text, numbers or icons.
• Ensure strong contrast between text and backgrounds.
• Test palettes with colour blindness simulators.
• Avoid red and green as the only difference between key variants.

Colour in print

A colour that looks right on screen may look different in print. Consider:

• CMYK vs spot colours: some bright colours cannot be reproduced in CMYK and need Pantone spot inks.
• Materials: colours look different on coated, uncoated and kraft board, films and wrap papers.
• Finishes: gloss, matte and soft-touch laminates change colour appearance.
• Consistency: the same colour on a box, a label and a pouch will vary slightly; aim for a consistent family.

Our Pantone vs CMYK guide explains how to manage this.

Colour online

Many products are first seen as thumbnails on screens. Colour on screen is affected by device settings, image processing and the surrounding page. Check how your packaging looks:

• as a small thumbnail in search results
• against a white background, as on many marketplaces
• in dark mode, if relevant
• beside competitors' thumbnails

Testing colours

Colour decisions should be tested, not just debated.

1. Check colour on real materials: use a 3D mockup for the look, and printed colour guides for the actual inks and finishes.
2. Create a shelf simulation: place your concepts among competitors, physically or digitally.
3. Ask customers to find your product and note how quickly they do.
4. Ask what the colours suggest about the product, price and brand.
5. Check thumbnails and online listings.
6. Test in different lighting, such as shop lighting and daylight.

Colour across markets

If you sell internationally, colour needs extra thought. Some colours carry strong associations in particular cultures, for celebrations, mourning, religion, politics or luck. A palette that feels fresh in one country may feel unusual or inappropriate in another. Category codes can also differ between markets.

Before launching in a new market:

• review competitor packaging in that market
• ask local partners or distributors for feedback, including retail buyers who know how the category is merchandised
• test with local customers where possible
• adjust secondary colours if needed while keeping your core brand colour, so the brand stays recognisable everywhere

Recording your colours

Once you have chosen a palette, record it in your brand guidelines with:

• Pantone references for coated and uncoated materials
• CMYK values tested on your main materials
• RGB and HEX values for screens
• rules for use: proportions, combinations and what to avoid
• approved printed references for each packaging type

Common colour mistakes

• Choosing colours by personal preference.
• Following category leaders so closely the product disappears.
• Too many colours, diluting the brand.
• Variant colours too similar to tell apart.
• Relying on colour alone for important information.
• Approving colour on screen.
• Ignoring material and finish effects.
• Ignoring cultural associations in new markets.

Questions

Do colours have fixed meanings on packaging?

No. Associations vary by culture, category and context. Use colour meanings as starting points, then test with your customers.

What is the best colour for packaging?

There is no single best colour. The right colour helps your product stand out in its category and fits your brand and price point.

How many colours should packaging use?

Many strong packs use one dominant colour with one or two accents. More colours can work but need careful hierarchy.

Should I follow category colour codes?

Partly. Category codes help shoppers find what they want, but owning a distinctive colour can make you easier to find.

How do I test packaging colours?

Show 3D mockups on a simulated shelf beside competitors, and check colour on printed guides. Check thumbnails too.

Do colours mean the same in every country?

No. Some colours carry different associations in different cultures, so check your markets.
