 Comment 1: @Maxiride Check out [this fork](https://github.com/giogziro95/arc-kde). I won't be updating it frequently, but, at least, it's usable.
 Comment 2: 

@varlesh There's an issue I'm having with the older version... I forked your repo reverted to e06279795dc92c02d8431c263d93d798c9acedd5, and updated the scripts as needed, but the text fields on the desktop theme have blue backgrounds:

Also, there's an issue with the background of _Active connections_ and _Available connections_ within the network manager plasmoid:

A few days ago, this wasn't like this. If this is not an issue with my setup, can you please tell me in which commit has this been changed? I'll have a look at the diff and sort it out myself.

Thanks!
 Comment 3: @giogziro95 Blue background used for new version too, because initialy Arc Dark Colors have wrong colors an more bugs.
You can compare colors and check this, extract to ~/.local/share/color-schemes [color-schemes.tar.gz](https://github.com/PapirusDevelopmentTeam/arc-kde/files/1293215/color-schemes.tar.gz)
Arrows not exist on old Kvantum themes, need update this.
 Comment 4: @giogziro95 See on up preview - it's Arc Dark OLD PLASMA colors:
