SoftWhite is a GTK theme, inspired from artrage, using the Clearlooks and Pixmap engines.
You can change the green highlight color through gnome appearance/customize colors.
I've also included a small script in the softwhite folder, named 'colorize' which will alter the scrollbar prelight pixmaps, and if found, the emerald theme button glow to the color of your choice.
Type './colorize RR GG BB' where RR, GG and BB are the red green and blue components of the color of your choice in hex.
