I will make a video on how to do this on a Mac OS X/Apple Computer in the future.
If you use Linux, you’re probably going to spend a lot of time in the terminal, and you might want to customize it to look how you want. In this tutorial, I’m going to be doing it in Ubuntu 20.04.2 LTS.
Open your terminal.
Depending on your application and shell theme, the terminal will look a bit different. View my article on how to change GNOME Themes on Ubuntu if you are interested in changing the system theme.
No matter what the system theme is, it will most likely look like a default terminal without any customizations.
To get to the customizer, right click in any empty space, and choose “preferences.”
You now have access to the preferences window. Just in case you’re not in the right place, make sure you asre under “Profiles.”
If you have never changed a theme, you will have only one option under Profiles. Next, choose the “Colors” tab at the top (the “Text” tab is pretty self-explanatory).
Usually, Use colors from system theme will be on. To customize it to however you want, disable that.
There are quite a few built-in schemes. You can choose one of them, or choose Custom to customize your own. Click on any of the color boxes and choose your color with the color picker.
Under Pallate, you can find other bulit-in schemes, as well as custom schemes.
You can change fonts in the Text tab. I made my terminal very transparent with other cool features as well.
For a more in-depth explanation on how to do this, see my YouTube video on how to do it.
