Test semantic surfaces separately
A single contrast score cannot validate an entire AI workspace.
- User and assistant messages
- Code blocks and inline code
- Added and removed diff lines
- Permission, warning and error states
Reduce visual competition
Choose a quieter package or static fallback when artwork competes with controls.
- Avoid bright detail behind code
- Keep sidebar boundaries visible
- Respect Reduced Motion
Report exact evidence
Record theme slug, client version, Adapter and a screenshot of the failing state.
Frequently asked questions
Should I edit raw CSS to fix contrast?
No. That is outside the supported declarative package path.
Is basic color tuning a CC Theme feature?
Use host-native Appearance first. CC Theme's differentiation is the prepared background package and verified Adapter path.
