Remove Top Line in TopBar

I cant for the life of me figure out how to remove a line that shows up at the top of my top bar above my logos.  I am using the atlas_default layout and there is a line as shown in the picture that always shows up depending on what my primary color is set to for my app.  A solution would be to make my primary color white, but then this messes with everything else in the app, mostly text colors that are set to primary and then i would have to go and edit each of them.   I feel like this is a dumb question but im actually lost here. Thanks.

Add the next lines to your custom stylesheet.

.layout-atlas .region-topbar::before {
    display: none;
