How randomness and fairness work
Random choices use browser cryptographic randomness and unbiased integer selection. Every eligible item or value receives equal treatment unless the tool explicitly uses weights or balancing rules.
Limitations
Contrast alone does not establish full accessibility; font size, states, color blindness, and surrounding UI also matter.
Questions about the Accessible Color Combination
Is the Accessible Color Combination free to use?
Yes. It can be used without an account or payment, and generation takes place in your browser.
