smiley.blue went online in August 2014. We are working on more blue smileys for free use as wallpaper, Facebook photos, icons, etc. and all these funny faces are ready to share for free too.
Basically all smileys on smiley.blue are blue. The colors used for the funny faces are chosen to match the Tango desktop palette.
We will keep trying to create funny smileys and serve them as free download for you. We also plan to create smileys which matching current events.
Once we have sufficient smileys available, we would make collections and plugins for e-mail and chat programs.
An icon collection for Windows is also on our blue todo-list ;-)
