Restore chapter description alpha (#8345)

Restore "Darken the description colors"

Restores #3858, with new values based on current standards (0.78f rather than 0.62f)

I wanted to accomplish this without having to call a const, but that felt like a logical solution as well

Of course, if you got cleaner methods do tell, thanks
