I am totally new at this and currently trying to finalize the look of the store. I have tried just about everything in effort to change the icon colors at the top of the page such as the cart & menu options. The background of my store is white and so are the icons. Though you can see the icons on the Home page, you are not able to see them once you move passed the Home page. Where and how can I adjust this? I am currently using the Brooklyn template.
