Bold Blue is meant to be a light colorful GTK theme for GNOME.
I've modded and used parts from Glossy P, the menu system from DarkCaramel and the buttons from Elegance. I've added my own menubar and toolbar.
I've bundled it with the Mazantigade Mark II metacity theme which goes well with this theme.
GNOME is an international effort to build a complete desktop environment-the graphical user interface which sits on top of a computer operating system-entirely from free software. This goal includes creating software development frameworks, selecting application software for the desktop, and working on the programs which manage application launching, file handling, and window and task management.
GNOME is part of the GNU Project and can be used with various Unix-like operating systems, most notably Linux, and as part of Java Desktop System in Solaris.
The name originally stood for GNU Network Object Model Environment, though this acronym is deprecated. The GNOME project puts heavy emphasis on simplicity, usability, and making things "just work".
