How can I change header color in Symmetry theme?

Topic summary

A Symmetry theme user is experiencing navigation visibility issues due to a black header making menu links invisible on certain pages.

Problem:

  • Header appears black after navigating to menu pages
  • Navigation links are not visible against the black background
  • User also wants to change the main page header color when scrolling

Solutions Provided:
Multiple community members offered CSS fixes:

  • Primary solution: Add CSS code to styles.css or base.styles file to change navigation link colors to black (#000) with !important flags
  • Code targets .navigation__link elements within #main-nav
  • Alternative approaches suggested editing theme.liquid file

Outcome:
The initial fix successfully resolved the navigation visibility issue. However, when the user requested to also change the header color on the main page during scrolling, one responder advised keeping it black to avoid visual inconsistency.

Note: The conversation includes code snippets and screenshot references that are central to implementing the solution.

Hi,

My website is using Symmetry theme.

I have an issue right now. My header is black color right now after going into all the menu pages. But I don’t know what going on this issue. The navigation is invisible. I would like to get some help. Also, how can I change the main page header color (black) when I am scrolling down? Thanks a lot.

@Kathy518 - please add this css to the very end of your styles.css file and check, it should solve this

#main-nav .navigation .navigation__link,
#main-nav .navigation .navigation__link:hover {color: #000!important;}

.template-index #main-nav .navigation .navigation__link,
.template-index #main-nav .navigation .navigation__link:hover {color: #fff!important;}

Hi,

Thanks a lot. It works. If I want to make the main page when I am scrolling down, the header become black color too. How should I do? thanks

@Kathy518 - better to keep black only else it will look weird
