Frequently asked questions
What does the Color Contrast Checker produce?
It uses interface scope, elements reviewed, checks completed (%), material failures found, test evidence to produce an input-linked output, evidence signal, and next action.
Does this replace user research or accessibility testing?
No. It structures supplied facts and assumptions. Validate important decisions with representative users, source evidence, assistive technology, or qualified review.
Does every field affect the result?
Yes. Every count, percentage, and written evidence field changes the calculated signal, structured output, explanation, or recommendation.
Is entered information uploaded?
No. Processing runs in your browser. Remove participant names and other sensitive information before entering research material.
