Choosing accessible color palettes for marketing materials

Color is one of the fastest ways to communicate a brand message, direct attention and create recognition. Yet a palette that looks attractive on a designer’s screen can become difficult or impossible to use for people with low vision, colour vision deficiencies or temporary viewing limitations. Accessible colour palettes help your marketing materials reach more people while making every campaign clearer, more consistent and easier to act on.

Accessibility starts with contrast, not colour preference

Contrast describes the visual difference between two colours, most often text and its background. A high contrast ratio makes words, icons and calls to action easier to distinguish. A low ratio can cause key information to disappear, particularly on small screens, in bright daylight or for readers with reduced vision.

The Web Content Accessibility Guidelines, commonly known as WCAG, offer practical targets. For standard body text, aim for a contrast ratio of at least 4.5:1. Large text can use a minimum ratio of 3:1. The same 3:1 threshold is useful for meaningful interface elements, such as button borders, form fields and chart lines.

You can check combinations with a free WCAG contrast checker. Test every frequently used pairing, including:

• Headings on coloured panels
• Body text over brand backgrounds
• Buttons and their labels
• Icons that convey an action or status
• Text placed over photography or gradients

Do not assume that a dark colour automatically has enough contrast against a bright one. Saturated red on black, for example, can be hard to read despite appearing bold. Pale yellow on white also tends to fail, even when it suits a cheerful campaign style.

A usable palette includes more than brand colours

A brand palette often begins with a logo and a few signature shades. These colours may be excellent for recognition but unsuitable for every practical application. Rather than changing the brand identity, you can build a broader working palette around it.

Start by identifying your primary brand colours. Then create darker and lighter alternatives that retain the original hue while offering reliable contrast. A bright coral may work well as a decorative accent, while a deeper burgundy version may be better for text. A pale blue could provide a soft background, paired with navy text rather than white lettering.

Neutral colours deserve as much attention as the main brand hues. Off-white, charcoal, deep navy and warm grey can support accessible layouts without making them feel clinical. They also create breathing room around vivid campaign assets.

A practical marketing palette usually contains:

1. One or two primary brand colours
2. Dark text colours that work on light backgrounds
3. Light background colours that work behind dark text
4. Accent colours for highlights and calls to action
5. Status colours for success, warning and error messages
6. Neutral shades for structure, spacing and long-form content

Keep the number of active colours manageable. Too many competing shades can weaken hierarchy and make colour meanings inconsistent across ads, brochures, landing pages and social posts.

Colour should support meaning, not carry it alone

Colour can quickly signal whether something is positive, urgent or unavailable. Green often suggests success, red can indicate errors, and orange may suggest caution. However, these associations are not universal, and many people cannot reliably distinguish certain colour combinations.

Whenever colour communicates meaning, add another visual cue. A form error can include a warning icon and a short message, not just a red outline. A sale graphic can combine a coloured badge with clear wording such as “20% off”. A chart should use labels, patterns or different line styles alongside coloured data series.

This approach also improves performance in black-and-white printing, low-quality displays and social media previews. If a promotional image loses its meaning when viewed in greyscale, the design needs stronger non-colour signals.

For charts and infographics, avoid placing red and green next to each other as the only distinction. Blue and orange often create better separation, but their contrast still needs checking against the background. Labels placed directly beside data points are usually more accessible than a distant colour-only legend.

Marketing formats need their own colour checks

A palette can pass a contrast test and still fail in a real campaign if it is used inconsistently. Marketing materials appear in varied sizes, environments and devices, so test the intended format rather than relying only on a desktop mock-up.

Social graphics need clear focal points

Social posts are often viewed quickly on mobile devices. Use strong text-to-background contrast, limit the amount of copy and keep vital information away from busy imagery. If text sits on a photograph, place it within a solid or semi-opaque panel instead of directly over changing details.

Email and web content need dependable states

Links, buttons and form elements need to remain identifiable in every state. A link should not rely on colour alone, so consider underlining it within body copy. Buttons should retain readable labels when hovered, focused or disabled. If a button changes from blue to a lighter blue on hover, check both versions.

Print materials need realistic proofs

Printed ink rarely matches an illuminated screen exactly. Request a proof when colour accuracy affects legibility, especially for pale type, metallic finishes or textured paper. Small text in reversed white type deserves particular care, since thin letterforms can fill in or blur during printing.

Your accessible palette can strengthen campaign results

Accessible colour choices are not a limitation on creativity. They establish a dependable visual system that lets your message, offer and brand personality come through without unnecessary friction. Use contrast as a design requirement, develop practical shades beyond the logo colours and provide cues that do not depend on colour alone.

Key points to carry into your next campaign include:

• Check contrast ratios for text, buttons, icons and meaningful graphics.
• Build light, dark and neutral variants around your core brand colours.
• Do not use colour as the only way to communicate status or action.
• Test social, email, web and print designs in their real viewing conditions.
• Treat accessible colour decisions as part of your brand system, not a final compliance check.
