I originally designed these icons while working on my first guiKit Samui 1.0. Since then a lot has changed and the old icons I released look really bad to me color wise. So I went to work refining the icons and this is what I came up with. You should be able to make about any color from the icons provided. PNG+ICO for windows and Icon+Pixadex for Mac.
