Your brand colors are a signature, like a storefront sign on a busy street. Poor readability harms web accessibility; if shoppers can’t read your buttons, prices, or promo banners, that signature turns into friction.
The good news is you don’t need a full redo of your brand color palette to meet WCAG color contrast. In most stores, the fix is more targeted: change where a color is used, add a small border, or give text a stable background. You keep the vibe, and your UI becomes readable in more lighting conditions, on more screens, for more people, including shoppers with visual impairment.
Understanding WCAG color contrast is essential for creating an accessible digital experience. Designers should prioritize WCAG color contrast to ensure all users can interact with the content comfortably.
Web Content Accessibility Guidelines 2.2 contrast rules that actually affect store UI
The Web Content Accessibility Guidelines 2.2 points to a few contrast checks that show up constantly in ecommerce.
Here’s the quick reference (Level AA is the usual target). If you want the detailed definitions and examples, MDN’s overview of WCAG contrast ratios is a solid companion.
Before the tactics, align on the numbers:
| What you’re designing | WCAG 2.2 Success Criterion | Minimum color contrast ratio (Level AA) | Plain-language meaning |
|---|---|---|---|
| Body text (most product copy) | 1.4.3 Contrast (Minimum) | 4.5:1 ratio | Text must stand out clearly from its background |
| Large scale text (18pt+ regular, or 14pt+ bold) | 1.4.3 Contrast (Minimum) | 3:1 ratio | Big text can be a bit lower contrast and still readable |
| Icons, input borders, focus rings, toggles | 1.4.11 Non-text Contrast | 3:1 ratio | Key UI shapes must be visible, not just “kind of there” |
| “Color-only” meaning (sale vs not sale, error vs success) | 1.4.1 Use of Color | N/A | Don’t rely on color alone to communicate status |
Two ecommerce gotchas matter here:
First, images of text (like “20% OFF” baked into a banner image) are treated as text. They still need contrast.
Second, the rules apply across states. A link that passes at rest can fail on hover if it turns light gray.
Before/after fix pattern (product page text)
Before: Price text uses your “muted gray” token on white, and fails 4.5:1 ratio.
After: Keep the same gray for secondary UI, but switch price text only to a darker shade. The page still feels on-brand, but the text contrast makes the numbers readable.
Keep the brand color palette, change where the color is applied
Most contrast failures happen because a brand color is used in the wrong role, not because the color is “bad.” Maintaining your brand color palette is fully compatible with accessible design principles. Brands often pick one bright accent, then try to use it for text, buttons, badges, and links. That’s where accessibility breaks.
A practical approach is to keep your palette, then define accessible variants by usage:
- Brand color for backgrounds and accents (marketing feel)
- A darker “brand shade” for text on light backgrounds
- A lighter “brand tint” using tints and shades for text-safe backgrounds behind dark text
- A neutral that always passes for body text
This is also why many design systems separate “brand” from “functional UI.” Even formal brand guides call out readability constraints, like UCLA’s notes on accessible color and type choices.
In ecommerce, these are the patterns that protect the brand identity across all UI components:
Text-only swap: Keep the button fill, change only the label color (or vice versa).
Micro-borders: Add a 1 to 2px border to define a button against similar backgrounds.
Underlines for links: Color alone is risky. Underlines make links obvious even when contrast is tight.
Containers behind text: A small pill, chip, or banner behind text often beats changing your hero image.
If you want more store-specific examples, this pairs well with WCAG color contrast guidelines for online stores.
Before/after fix pattern (CTA button)
Before: Primary CTA uses brand green with white text, but the combo misses the required 4.5:1 color contrast ratio.
After: Keep the green fill, then either (1) switch label text to near-black, or (2) use a darker green shade for the fill while keeping white text. If you can’t change either, add a subtle 1 to 2px dark border and increase label weight so the CTA still reads as “primary.”
Contrast failures that hit conversions (and the fastest fixes)
Contrast problems in interactive elements aren’t spread evenly. They cluster in a few high-money places.
Effective implementation of WCAG color contrast can lead to a smoother user journey on your website.
Integrating WCAG color contrast techniques can significantly enhance user engagement, leading to improved conversion rates and a better shopping experience.
Consider the role of WCAG color contrast in achieving better accessibility for users with visual challenges.
CTA clusters (home, PDP, cart):
Buttons sit near other colored blocks, badges, and images. When everything is “loud,” the CTA can become invisible. Also check secondary buttons, like “Save for later,” since low-contrast ghost buttons often fail 1.4.11.
By applying the principles of WCAG color contrast, designers can create visually appealing interfaces that remain functional and user-friendly.
Prices and small metadata:
Designers love light gray for “elegant” price styling. Meanwhile, shoppers with color blindness scan price faster than any other text. If you only fix one text style, fix price and availability.
Promo banners: text over images
Hero images change, so contrast changes. That means your “Free shipping today” text might pass on one photo and fail on the next.
States people forget:
Hover, active, visited links, disabled buttons, and focus indicators. WCAG 2.2 doesn’t care that your default state passes if the focus ring disappears, which hurts WCAG compliance.
For a clear breakdown of how 1.4.3, 1.4.11, and 1.4.1 fit together at AA, see contrast requirements for WCAG 2.2 Level AA.
Before/after fix pattern (text on hero photo)
Before: White promo text sits directly on photography, passing sometimes and failing often.
After: Add a subtle scrim behind the text (a dark overlay at 20 to 40% opacity), or place the text in a semi-opaque chip. Your brand photography stays, but the message becomes stable across image swaps.
The focus on WCAG color contrast not only meets legal requirements but also serves to enhance brand reputation.

Gotcha: If your focus ring is low contrast, keyboard users can lose their place during checkout. That’s not a “nice to have,” it’s a flow-breaking bug.
A testing workflow that won’t start a brand war (plus checklist and decision tree)
Start with the screens that drive revenue: home, collection, product, cart, checkout, and account. Then test the components that repeat: buttons, form fields, links, badges, price styles, and banners.
For platform-specific guidance, Shopify teams often reference WCAG compliance for Shopify stores when scoping fixes with developers. WooCommerce teams can also align dev work with WooCommerce accessibility best practices.
Keep your workflow simple. Use contrast checker tools like the WebAIM contrast checker for precise web accessibility checks:
For those seeking guidance, WCAG color contrast resources are readily available to help navigate compliance.
- Test default and interactive states, not just static mocks
- Check contrast at real sizes (mobile text often drops below “large text” rules); rely on contrast checker tools for verification
- Log failures by component using hexadecimal color values, not by page, so fixes scale
- When you create accessible variants, name them by role (for example, “Brand Text on Light”)
APCA and WCAG 3 are emerging and may change how contrast is measured later. For February 2026 work, most teams still target WCAG 2.2 ratios for compliance.
Using reliable tools to verify WCAG color contrast ratios is crucial for maintaining design integrity and compliance.
Before/after fix pattern (icon buttons and inputs)
Before: Search icon and input border are light gray on white, failing 3:1 for non-text contrast.
After: Darken the icon and border, or add a stronger 1px outline. If the UI feels “too heavy,” reduce thickness elsewhere instead of lowering contrast.
Quick checklist for WCAG color contrast in ecommerce
Identifying the challenges of WCAG color contrast is the first step toward creating a more inclusive online environment.
- For WCAG compliance at Level AA, body text meets 4.5:1 ratio, large text meets 3:1 ratio
- Price, totals, and error messages meet 4.5:1
- Icons, form field borders, toggles, and focus states meet 3:1 for non-text contrast
- Links aren’t identified by color alone (underline or other cue)
- Promo text over images has a scrim, chip, or solid container
- Hover, active, disabled, and focus states are tested and pass
- Images of text (sale badges in banners, graphical objects) are treated as text and checked for color contrast ratio at Level AA
Incorporating WCAG color contrast principles into every design phase can yield significant benefits.
Make it a priority to regularly assess WCAG color contrast compliance as part of your design process.
Ultimately, embracing WCAG color contrast enhances both usability and accessibility for all users.
By aligning your design strategy with WCAG color contrast guidelines, you create a more welcoming environment.
Decision tree, what to change first
In conclusion, integrating WCAG color contrast throughout your designs promotes inclusivity and usability.
- Can you change the background behind the text? Add a chip, scrim, or solid panel first.
- If not, can you change only the text color? Use a darker text shade for readability.
- If the text must stay, can you adjust size or weight? Large text can pass at 3:1.
- If none of that fits, can you add a border or outline? Especially for buttons and inputs.
- Last resort: Use an extended palette for that UI role (keep marketing colors elsewhere).
Accessible contrast shouldn’t feel like a brand compromise. Done right, it’s a clarity upgrade that shoppers notice as “easy to buy from,” while delivering SEO benefits and reducing legal risk for better web accessibility. Treat WCAG color contrast like typography: a system choice that makes every template work harder, boosts web accessibility, improves user experience across UI components, and supports WCAG compliance with optimal color contrast ratio.
Awareness of WCAG color contrast requirements is essential for web designers and developers alike.
A checklist for WCAG color contrast compliance can guide teams through the necessary adjustments to enhance accessibility.
Ensure that all elements adhere to WCAG color contrast standards to create an inclusive website.
Remember, WCAG color contrast should be a key consideration in every digital project.
