Inability to define colour schemes

Topic summary

A user is experiencing an issue customizing header colors in Shopify’s Dawn theme while using a third-party page builder. The theme customizer displays an error message preventing color scheme modifications.

Attempted Solution:

  • Another user suggested following a video tutorial on changing color schemes
  • The original poster attempted to modify the theme’s JSON settings file directly

Current Status:

  • The user reports encountering a “huge error on the last line” of their JSON code
  • They’ve shared a code snippet from what appears to be cart settings configuration
  • The code includes a typo: "sho w_vendor" (space in the middle)
  • The discussion remains unresolved, with no confirmation whether the JSON error is related to the original color scheme issue or if fixing the syntax will resolve the customization problem

I am currently using an alternative application to build my page, though I am using the basic dawn theme for the global header, as well as the checkout page. Problem is, when I am attempting to customize my header, the message below pops up. This does not allow me to customize the colours of my header, and I’m wondering if anyone may know the solution.

This is inside the theme settings.

This is at the top of the header
