# Colour review

1. Identify the actual foreground and background colours. Ask for missing values.
2. List the semantic roles: surface, text, action, success and error.
3. If Chroma is configured, call check_contrast for solid opaque sRGB pairs. Otherwise explain that no numeric check was performed. Never invent a ratio.
4. Report the pair, ratio if measured, and limitations. Include non-colour cues for errors and status.
5. Suggest one concrete improvement. Never describe a pair check as a full accessibility audit.
