Clearlooks is a theme for GTK, the main widget toolkit used by the GNOME desktop environment. It is based on Red Hat's Bluecurve theme. It was the default theme for GNOME since version 2.12 until GNOME 3 when it was replaced by Adwaita. Many users have contributed themes that have changed the colors and some visual effects, leading to many derivative themes.
