Accessibility

It is essential that all visitors to your website can access the content without technical or user-related hurdles.

Accessibility means that products, services, and information are designed so that everyone—regardless of disabilities—can use them without additional hurdles. This may sound challenging, but Say Hello helps you avoid common problems and comply with legal requirements.

Costs

Ensuring that accessibility is part of the initial concept for a project usually means that no additional costs will be necessary for work I carry out. Leaving accessibility to a later stage can often mean rebuilding and even redesigning parts of the website, which will add to the overall project budget.

Don’t treat accessibility like trying to put chocolate chips into a cookie after it is baked.

Consulting for designers and agencies

Good color contrast is one of the most important foundations for accessible websites and apps. When bright colors are placed on a light background, they can be difficult to see – for example, depending on the screen, if you have color vision deficiency, or if you have eye problems.

We adhere to best practices in the conception and design of our projects. Say Hello also offers consulting services for designers and other agencies working on web projects.

Who is affected?

A website visitor with special needs doesn’t necessarily have a clearly identifiable physical or mental disability. Perhaps the person has difficulty seeing certain colors or understanding complex visualizations.

Perhaps their brain is sensitive to animations, or they might simply be trying to navigate a website with one hand—while holding a squirming baby or holding on to something on public transportation.

Even simple things like wearing glasses or having to read content in a dark room can present challenges that web designers and programmers need to consider.

Legal requirements

The European Accessibility Act (EAA) has been mandatory in the member states of the European Union since 2025. Starting this year, websites and online shops that serve customers in the EU must meet accessibility requirements. For example, an online shop operated in Switzerland that also delivers to customers in the EU must also meet accessibility requirements.

Measurement of this website

WCAG 3.0 Rating 4 – Meets or exceeds the APCA lookup table values.

Further information

The Advanced Perception of Color Algorithm (APCA) considers the context in which colors are used to determine their readability. Font size, font weight, and the order of background and text colors influence the recommended contrast value (LC) for text.

APCA was included in earlier drafts of the WCAG 3.0 guidelines for text contrast. The proposed ratings were based on the proximity of the calculated contrast value to the target value in the APCA lookup table. While the final role of APCA in WCAG 3.0 is still unclear, the APCA Readability Criterion (ARC) is currently being developed as an independent standard for visual contrast. For more information, see the public ARC draft.
