Low-contrast text is hard to read

I really like this theme, but I think the pink background color should be a little lighter to better distinguish the letters of the tabs, the side menu and the application menu (the 3 lines at the top right); In addition, I do not give 5 stars because when I open the side menu of bookmarks "ctrl + b", or the history "ctrl + h", if I click outside of them is not marked the last one I selected previously. By the way, it is a great detail to put color when I open a new tab and when I open the application menu.
If these 2 little things are solved I would give 5 stars, also something similar happens with the other purple theme created.
Greetings.
