I change the colors of greybird, I use the color scheme from: orion, elementary and zukitwo, I use some parts of bluebird and did a variation of greybird with dark menu bar.
Did all the xfwm over zukitwo's xfwm to work with orion color (lightbird). They were taken from metacity from zukitwo, greybird-mac, greybird, fundamental round, a screenshot of kde and a screenshot from a mac, and use the idea of Lucid Spotlight. The black menu bar have its own xfwm with hope buttons. there's a panel image included from eno gtk.
icons used in the preview faience-azur with lambda in thunar right side pane.
