Thanks for the general answer, but my question is more specific to how can I change the color of the hamburger icon declaratively in the Theme settings for "Growth" theme. I have looked through the settings and cannot find it.
You can change the hamburger menu color in the Growth theme by navigating to Settings > Website > Themes > Growth Themeand adjusting the Navigation or Header color settings. If there's no direct option, you may need to add custom CSS in the Design Tools under the theme’s stylesheet.
