Harmony

img0, officially known as Harmony is the default wallpaper of Windows 7. It is a colorful Windows flag with flat trees, butterflies and grass surrounding it, on a blue background with some flat plants. It was created by Chuck Anderson and Erik Attkisson, who also created the logon background. The wallpaper has seven leaves, seven branches, and seven flower petals in the Windows logo.

History
Rather than creating default and logon wallpapers themselves or buying all of the rights to a stock image, Microsoft contacted young artist Chuck Anderson about creating the default and logon wallpapers for 7 in December 2008. The design team showed him wallpapers by other artists involved with 7's wallpapers, and were open to his ideas for the wallpapers. Both works took four months to create. He started them using pencil and paper, before shifting to Photoshop. He also used a Wacom tablet for drawing the individual threads, helping to give them a sketchy feel.

Rejected versions
There are four rejected versions of img0, along with four rejected versions of the logon background. They were intentionally released at a maximum vertical height of 768 so that they would be too small for most modern displays, although they are still big enough for displays like older monitors or netbooks.

Legacy
Microsoft would later hire Anderson to create a theme titled Surreal Territory in 2010.

Due to the popularity of Windows 7, the wallpaper has become iconic, although not to the same extent as Bliss. Much like Bliss, it has also received several meme edits, such as one where Doge is edited onto the logo.
