A subtle color pairing can feel elegant on a large display in a quiet room. The same text may be harder to read on a smaller screen, in changing light, or for a reader with different visual needs.
Check contrast with the actual foreground and background colors used by the interface. Include muted text, links, and states that appear after interaction. Do not assume that a theme remains readable because its main heading has strong contrast.
Use contrast alongside clear labels and other visual cues. Color alone should not carry an important distinction. A readable design gives ordinary content the same care as the most prominent part of the page.
- Check body and supporting text.
- Review interactive states too.
- Use more than color for important distinctions.
A small working example.
Imagine reading muted text beside a sunny window. Checking ordinary contrast conditions can reveal information that was only comfortable in a dark studio.
A note to keep beside it.
Review the longest word and the least convenient condition. An interface should have room for the ordinary variations that a polished sample often leaves out.
