When is the result reliable?

How does Contrast checker calculate?

Contrast checker uses this visible logic: Farben werden in RGB normalisiert; Kontrast nutzt relative Luminanz. Example values and common mistakes are shown next to the tool.

Do inputs stay local?

Yes. The calculation runs in the browser. Toolwise does not send inputs to a server or load external calculation modules.

What should I do next?

Copy the result or pass it locally to Hex to RGB if you want to continue the workflow.
