# Color combinations

Inspect every combination of the default text and background colors, including the default color, applied to whole blocks and inline content. Switch between light and dark themes to compare their appearance.

**Try me out!** Use the theme toggle above the editors.

Point the example's source guard and core/react aliases at the repository root.

From examples/04-theming/08-color-combinations/, ../../ resolves to examples/, not the repository root. The existence guard therefore fails inside the repository, and the config selects empty aliases. @blocknote/core and @blocknote/react then resolve through the installed packages, not packages/core/src and packages/react/src, so live source changes are not loaded. Use ../../../ for the guard and for those two aliases. The @shared alias already uses ../../../.

This file is marked as generated. Regenerating it from packages/dev-scripts/examples/template-react/vite.config.ts.template.tsx produces the same change, because the template already uses ../../../.

Review comment at @examples/04-theming/08-color-combinations/vite.config.ts
around lines 15 - 16:
Update the generated Vite config’s source-existence guard and the
`@blocknote/core` and `@blocknote/react` aliases to resolve from the repository
root using the same `../../../` base as `@shared`. Keep the build-command
behavior unchanged, and make the corresponding change in the source template so
regeneration preserves it.
