Arc Black Ubuntu

This is my attempt at making the arc-theme at bit more unity-friendly, with (in my opinon) better colors.

Theme now supports xfce, thanks to - Please open an issue, if you find some bugs.

This theme is build with GTK2 + GTK3.18 in mind, so it's for xubuntu + ubuntu unity 16.04 ONLY. - If you dont like OSX icons, you can use the orignals with theme noOSX.

Theme is a fork of - Thanks to horst3180 for his wonderful theme.

If you have more suggestions feel free to ask or make pull-requests.

You will need to install gnome-themes-standard & gtk2-engines-murrine to make sure everything works.

Changes made

  • Changed from blue to black (#2f2f2f)
  • Made text white insted of gray-ish.
  • Made default text darker, so it's easier to read.
  • Changed nautilus + GtkFileChooserDialog to have a less dark sidebar.
  • Made two versions, with and without OSX buttons.
  • Disabled transparency
  • Made the unity top bar the same color as other windows.
  • Deleted all non-unity stuff
  • Made menus black/white instead of white/black, which made some problems for the unity top bar - icons would not show in the correct color. - White icons on white background is ugly :)
  • Made scrollbar for terminal dark
  • Added default terminal colors, to better fit the the rest of the theme.
  • Added unity-greeter theme.
  • Added line separators for menus and nautilus sidebar.
  • Alot of other things I really can't remember.
