Oranchelo is a very well made theme for the icons in Ubuntu.
Theme icons Oranchelo for Ubuntu 18.10
Oranchelo is theme icons with a flat design, originally developed for desktop XFCE4. Although it works fine in GNOME. I especially like the icons for Firefox and Chromium, as you can see in the screenshot.
Here’s how you can install icon themes in Ubuntu Oranchelo 18.10 using Oranchelo PPA.
Just copy and paste the following three commands in terminal (CTRL + ALT + T).
sudo add-apt-repository ppa:oranchelo/oranchelo-icon-theme sudo apt update sudo apt install oranchelo-icon-theme
Now run GNOME Tweaks (Add. Gnome settings), appearance > Icons > Oranchelo.
So how do you like the new icons? Write in the comments.
