### Cause

This is probably related to issue [NEXT-21038](https://github.com/shopware/shopware/blob/v6.6.9.0/changelog/release-6-6-9-0/2024-06-19-add-scss-validator.md), which was implemented in version 6.6.9.0 and in which a *SCSSValidator* was implemented.

Previously, empty color fields took a fallback color value from the SCSS theme. Now, empty color fields will throw an SCSS error and the theme will no longer compile. You can find more information in the [Theme save error](/en/faq/known-issues/theme-save-error.md) article.

### Solution

Check the color fields theme configuration for empty fields and enter a color or the value `transparent` here.
