Starting questionHow usable is a website really, for every user, in both colour modes and on every screen size?
What we did
We tested 32 pages automatically in two colour modes and four screen widths: performance, accessibility, contrast, multilingual content and layout.
After the fixes, contrast errors dropped by around 70 percent and language errors by around 62 percent. Remaining work stayed open and was named.
What it means for business architecture
Accessibility is a requirement you can measure. Automating it repeatably turns it into a quality gate rather than a one-off exercise.
Learnings
- A light and a dark mode double the test scope. Errors often cluster in one of the two.
- Before-and-after measurements make progress provable.
- Open issues belong explicitly in the report, not under the carpet.
