Improve Accessibility with Contrast and Focus

Learn how the right contrast, focus, and size improve user experience and help meet EAA and WCAG standards across web, mobile, and kiosk platforms .

Introduction

Design is not just about visual appeal. It is about making things work for everyone. When users cannot read your text, interact with a button, or tell which item is selected, they are effectively excluded. These are not small oversights ,they are the difference between accessibility and inaccessibility.

Contrast, size, and focus may seem like minor elements in a design system, but they have a major impact. These factors bring clarity and consistency, especially for users with visual or motor-related impairments. Whether navigating a website or a mobile app, these structural components help create inclusive digital experiences. User1st approaches design with accessibility in mind, giving teams the tools they need to prioritize these core design functions from the start.

Establishing Proper Contrast and Size

When text fades into the background or icons appear too faint, users with even mild vision challenges may have trouble engaging. Setting the right contrast is about more than visual taste. Higher color contrast directly supports readability and helps users identify components under different lighting conditions or device settings.

Here are effective ways to approach contrast and size in your interface:

1. Maintain clear contrast ratios between text and its background. WCAG 2.2 provides useful benchmarks that guide developers in choosing accessible color combinations.

2. Do not rely on color alone to convey meaning. For instance, red text signaling an error can be confusing without supplementary indicators like icons or written labels.

3. Set minimum dimensions for interactive elements, especially for mobile devices. Touch targets should be large enough to support fingers, not just cursors.

Use design tokens to apply these practices consistently. Embedding contrast and size decisions within tokens enables scalable and unified accessibility across your products, whether they are web-based, mobile, or kiosk interfaces.

Enhancing Focus in User Interfaces

Focus indicators show a user where they are within the interface. Whether using the Tab key or assistive technologies such as TalkBack or VoiceOver, these cues help people orient themselves and complete tasks confidently. Lack of focus feedback creates confusion and breaks usability.

To strengthen the focus experience:

1. Apply visible, consistent outlines or highlights for focused elements.

2. Include every interactive element in the focus path, such as buttons, form inputs, and links.

3. Avoid giving focus to non-interactive or hidden elements.

4. Incorporate native HTML elements like button and input where possible. Avoid replacing these with custom code that may interfere with assistive tech.

5. Ensure flow matches a logical, human-friendly navigation pattern. Top-to-bottom and left-to-right movement helps users understand layout quickly.

In complex or large-scale projects, common issues like skipped focus elements or invisible indicators often appear. These mistakes are more likely when teams modify default behavior or fail to test focus paths thoroughly. By using tools that identify missing focus states or broken accessibility workflows early, teams strengthen compliance with standards like the European Accessibility Act (EAA). That regulation reinforces the importance of interfaces being perceivable, operable, and understandable , just like WCAG.

Design Decisions That Make a Difference

Contrast, size, and focus are not surface-level styling choices. They are foundational elements that influence usability for everyone and critical access for those with specific needs. When you address these areas in your design tokens, you move closer to a system that works across devices, platforms, and use cases.

Think about how people read on the go, scroll with one hand, or rely on voice input. Their ability to succeed depends on how well you define and apply these three elements. It is not just about compliance ,it is about creating a better experience for as many people as possible.

Making smart decisions early around contrast, size, and focus leads to both accessible design and stronger product performance. When design accounts for clarity, visibility, and navigation, digital products start to work better for everyone.
