I have long thought that there should really be a teal version of the Shiki-Colors GTK themes, the GNOME-Colors icon themes, and Arc-Colors GDMs & wallpapers. If you've been wishing the same thing yourself, then your wish has just become reality.
The file consists of the Shiki-Ocean GTK theme, the GNOME-Ocean icon theme, and the Arc-Ocean GDM themes (regular and userlist).
NOTE: For the GNOME-Ocean icon theme, make sure you have the "gnome-common" icon theme installed, or else, in Vic's words, "clowns will eat you".
Many, many thanks to Victor C., aka "PerfectSka04" for his creation of the Shiki-Colors, GNOME-Colors, and Arc-Colors series of themes.
