papirus-folders VS adapta-kde

Use Papirus icons. Then you can use papirus folders. Papirus-folders is a bash script that allows changing the color of folders in Papirus icon theme and its forks. There are other icon themes which allow folder colour switches. Also there is no need for an extension, says the vanilla Gnome user 😉

Icons are Papirus icons and just using Papirus-Folders to change the folder icons to match the theme.
