Accessibility review guide

When your interface cannot rely on color alone

This page is not for “diagnosing design.” It exists to help teams understand where flows rely too heavily on color and where labels, icons, wording, or structure should carry more meaning.

Use screening as a design prompt

It can help teams notice more quickly when a flow depends too heavily on color differentiation.

Do not treat it as a substitute for user research

Real accessibility decisions still require design review, semantic checks, and feedback from real users.

Let the result drive interface alternatives

If the screen suggests red-green confusion may matter, review icons, labels, wording, and contrast hierarchy instead of relying on color alone.

How to use this in a design review
The goal is not a pass/fail verdict. It is to spot color-dependent moments faster.

1. Identify color-only meaning first

Look for states, charts, or success/error cues that depend on red-vs-green color alone.

2. Add redundancy beyond color

Add copy, shape, iconography, or structure so the flow remains understandable even without color cues.

3. Validate with real user feedback

An online screen only gives the team a direction. Final design decisions still need validation with real users.

Why would accessibility teams care about a color-vision screen?

Because many interface failures are not about aesthetics. They happen when color is the only carrier of meaning. Screening pages help teams enter that discussion faster.

Can it prove an interface is accessible?

No. It is only one signal that points teams toward areas that deserve deeper review.

Who benefits most from this page?

It is especially useful for product managers, designers, frontend engineers, and design-system reviewers.
