Choosing your brand's colour palette: a 2026 guide for SMEs

The real impact of colour on a brand

A 2025 HBR study found that consistent brand colours increase brand recognition by 80%. A well-chosen palette, used consistently, is worth as much as an advertising budget.

Conversely, a badly chosen palette, or one used inconsistently, dilutes everything: your website, your business cards, your social media posts and your sales slides do not communicate the same brand. Customers perceive a lack of professionalism, even unconsciously.

To find out how to choose a palette that lasts 5 to 10 years, follow these five steps.

Step 1: Define the role of each colour

An SME brand palette includes 4 to 7 colours with distinct roles:

Primary colour (1 colour): the main colour of your brand. Used for CTAs, accent elements and overall branding. For Voren, it is signal-lime #D2FB50.

Secondary colours (1 to 3 colours): used for variations, secondary backgrounds and states (hover, active). Often derived from the primary (darker/lighter versions).

Background colours (1 to 3 colours): for backgrounds. Often neutral (white, black, grey, beige). For Voren, dark base #08090A.

Functional colours (3 to 5 colours): for system states: success (green), warning (orange), error (red), info (blue). Chosen because they are universally recognised.

Text colours: black, grey, white, with calibrated contrasts.

Total: 4 to 7 main colours + ~5 functional colours = around 10 colours in the complete palette.

Step 2: The selection method

A: Start from your brand

Three framing questions:

• What is your brand’s tone? Premium, accessible, cheerful, serious, technical, creative?
• Which sector? Medical (blues/whites), finance (blues/dark tones), creative (bright colours), luxury (blacks/golds), tech (greens/lime), etc.
• What differentiation? If all your competitors use navy blue, choosing navy blue = blending into the crowd.

B: Inspiration

Useful tools:

• Coolors.co: generates harmonious palettes
• Adobe Color: a colour wheel with rules (analogous, complementary, triadic)
• Brand Color Tester: to see how your colours interact
• Awwwards: award-winning sites, with their palettes on show

Inspiration to avoid: copying a direct competitor’s palette (you will be mistaken for them) or following trends (Pantone Color of the Year, etc.: too dated within 2 to 3 years).

C: Test in a real context

A colour tested on its own and the same colour tested in a real context give very different results. Test your palette on:

• A website mockup (header, body, CTA, footer)
• A social media post mockup (Instagram, LinkedIn)
• A business card (front and back)
• An email signature
• A logo on different background colours

If the palette holds up on all these media, it is approved.

Step 3: Test accessibility

Accessibility is non-negotiable in 2026. The reference standard is WCAG (level AA), and since June 2025 the European Accessibility Act has required accessibility from online shops selling in the European Union.

WCAG AA contrast: a minimum of 4.5:1 between text and background for standard text. A minimum of 3:1 for interactive elements (buttons, links).

Testing tool: Contrast Checker (https://webaim.org/resources/contrastchecker): enter 2 colours, and see the ratio and the WCAG pass/fail verdict.

Colour blindness: 8% of men and 0.5% of women are colour-blind (mostly red-green). Test your palette with a simulator (Coblis Color Blindness Simulator) to check that it still works.

Common mistake: choosing a palette that pops visually but does not meet WCAG on the CTAs. A light grey CTA on a white background will not be clickable for 20% of users.

Step 4: Document the codes

Each colour must be documented in 4 formats:

• HEX: for the web (#D2FB50)
• RGB: for screens (210, 251, 80)
• CMYK: for print
• Pantone: for precision print (textiles, packaging)

These 4 formats are mandatory in the brand book, because print and web do not render colours in the same way. A printer who receives only the HEX code will have to convert it themselves, with possible discrepancies.

Tool: Pantone HEX converter (https://pantone.com).

Step 5: Define the combinations

The brand book must also define the permitted combinations of these colours:

• Which CTAs on which backgrounds?
• Which text on which backgrounds?
• Which combinations to avoid (weak contrasts, excessive vibrancy)?

For Voren: signal-lime on dark base (approved), signal-lime on white (approved with a black outline), signal-lime on a photo (approved if the photo is calm), signal-lime on lime (forbidden).

Common mistakes

Mistake 1 · Too many colours. An SME palette of 15 colours is unmanageable. Nobody remembers which one to use when. 4 to 7 main colours at most.

Mistake 2 · Colours that are too trendy. Pantone’s 2024 “Peach Fuzz” will look dated in 2027. Choose colours that are timeless or consistent with your sector.

Mistake 3 · Ignoring print. Your palette must work in digital as well as in print. Test printing before you lock the palette.

Mistake 4 · Colours that are too close. Having two very similar shades of blue (difference < 10% in HSL) creates confusion: it becomes impossible to know which one to use in a given context. The colours in your palette must be clearly distinct.

Mistake 5 · No colour-blindness test. 8.5% of your audience may have altered colour vision. A palette that works only for people who are not colour-blind excludes a significant share.

The Voren signal palette

For reference, the Voren palette:

• Primary: signal-lime #D2FB50 (CTAs, accents, branding)
• Dark background: dark base #08090A (main background)
• Mid background: #1A1B1F (cards, surfaces)
• Main text: white #FFFFFF (on a dark background)
• Secondary text: light grey #A0A0A0
• Success: green #4ADE80 (status OK)
• Warning: orange #FB923C (alerts)
• Error: red #EF4444 (errors)

In total, 8 colours: the contrast ratio meets AA throughout, and the palette has been tested for colour blindness.
