Colors in future content

Hello
In the Future Content area, I have set it up so that the title topics are light blue and when I hover over them with the mouse, they become dark blue. However, the color when I click on it cannot be adjusted. Can I set the text to turn orange when I click on it? The same problem is with the button on this page. This should also be orange when I click on it.

Many thanks for the help.
