Users upgrading to Dawn theme version 11.0.0 encounter an error: “No color schemes defined. Color schemes must be defined in settings_data and settings_schema files.” The color customization options are missing from the theme editor.
Multiple solutions have been proposed:
Code insertion method: Edit config/settings_data.json, locate "content_for_index", add a comma after it, and paste a complete color schemes JSON object with predefined color values (background-1, background-2, inverse, accent-1, accent-2).
Revert to original: Navigate to Theme settings > Config > settings_data.json > Recent changes dropdown > Select “original” to restore working configuration.
Fresh download: Installing Dawn 11.0.0 from scratch (rather than upgrading) avoids the bug entirely, though customizations must be redone.
Copy from GitHub: Replace the entire settings_data.json content with the official version from Shopify’s Dawn repository on GitHub.
Current status: The issue appears to stem from the upgrade process rather than fresh installations. Official Shopify support recommends contacting their team, though some users report support was unhelpful. Several users confirm the code-based fixes work, while others encounter “invalid token” errors or cannot save changes. The discussion remains active with ongoing troubleshooting.

I downloaded the latest version of Dawn 11.0.0 and I don’t have an option to change the color scheme. It says “No color schemes defined. Color schemes must be defined in settings_data and settings_schema files.” I see no instruction on how to add the color scheme.
We understand color schemes play a crucial part in branding. We’ve confirmed with the theme support team that the customization would require contacting support to be done. This ensures that the storefront functions as expected.

Hi - I have this issue as well. The problem is I also cannot contact the support team - the bot gives me a link which doesn’t work. I do not see the ‘I still need help’ button..
I’m not part of the Shopify support team. However, if you type “Talk to someone” that gets you a bit further and the chatbot will ask you to select a store and hopefully that will get you to a support person.
