Better contrast along Toolbar and Sidebar

[Cliff411]

I find the readability of my favorites bar and sides bar to be poor. The cause, at least in my view, is the colour used for the fonts doesn't contrast well with any background colour used in these two bars. In comparison, both Vivaldi and Firefox have very good readability contrast in the Toolbars and sidebars. Can I somehow fix this issue without any advanced technical ability?
