Gnome Colors
 

I am new to gnome,I am used to kde where you can change the color scheme of the title bars and so forth with ease.I have yet to find this preference in gnome.I also have downloaded some themes from art.gnome.org but after installing them they dont seam to affect the colors at all(The way their repective screen shots shows them, in other words).I am running Mandrake 9.1.
This may be a very simple question but thats why I thought it could help to post it.

doing this by a little memory, haven't worked with gnome for a bit.

click the cleverly disguised G (disguised as a foot I mean), click configuration, gnome, and theme settings, or it could possibly say themes. Hope thats it!

Run gnome-theme-manager from the command line.
