Okular has an odd choice of font and background colors in some places and this makes it difficult to read some text.
I looked at the settings and searched online but couldn't find anything on changing this.
What can I do?

You need to change the theme for Qt apps.
This can be achieved in two ways, with qt5ct
and kvantum
(don't use both of them together).
Install Kvantum with
sudo apt install qt5-style-kvantum
Now make KVantum as the default theme manager for Qt apps.
echo "export QT_STYLE_OVERRIDE=kvantum" >> ~/.profile
Reboot.
Now open Kvantum Manager, and apply a suitable theme.
Install qt5ct with
sudo apt install qt5ct
In Ubuntu 22.04, you will also have to install qt5-style-plugins
sudo apt install qt5-style-plugins
Now make qt5ct the default theme manager for Qt apps.
echo "export QT_QPA_PLATFORMTHEME="qt5ct"" >> ~/.profile
Reboot.
