<!-- Answer --> This is a known issue with how Superset handles shared label colors across dashboard charts. The behavior you're seeing is likely caused by leftover `shared_label_colors` or `map_label_colors` metadata in your dashboard, not the `SHARED_COLORS` flag (which doesn't actually exist as a feature flag). **Why this happens:** When multiple charts on a dashboard share the same categorical labels (e.g., cluster names like "1", "2", "3"), Superset [automatically tracks these in dashboard metadata](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/src/utils/colorScheme.ts#L58-L78) to maintain color consistency. This locks the color scheme dropdown and shows "Dashboard scheme" for affected charts. Your ~5 affected charts likely share labels with each other or other charts, while the ~20 working charts have unique labels. **Workaround - Clear Dashboard Color Metadata:** You can use the [dashboard colors API endpoint](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset/dashboards/api.py#L764-L844) to reset the color mappings: ```bash curl -X PUT "http://your-superset-instance/api/v1/dashboard/{dashboard_id}/colors"; \ -H "Content-Type: application/json" \ -H "Authorization: Bearer {your_token}" \ -d '{ "label_colors": {}, "shared_label_colors": [], "map_label_colors": {}, "color_scheme": "", "color_scheme_domain": [] }' ``` After clearing, do a hard browser reload (Ctrl+Shift+R) and re-save the dashboard. This issue has been [reported](https://github.com/apache/superset/issues/37711) and [discussed](https://github.com/apache/superset/issues/33839#issuecomment-2990202339) by other users in similar scenarios. A maintainer acknowledged this as unintended behavior where dashboards override chart colors even when the dashboard scheme appears empty. <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
