OK, so it IS blue. This is for those of you who don't like other colors. This is the matching splash screen for the "It's Not Blue" Slate wallpapers.
Simply extract the gzipped tar file to /usr/share/apps/ksplash/Themes or wherever your splash themes are. It will create a folder called Not Blue Slate. Then go to the KDE Control Center and select the Not Blue Slate theme.
All artwork is original. The icons are from the Aqua Fusion theme.
