Everaldo Coelho (Portuguese: [eveˈɾawdu kuˈeʎu]; born March 25, 1978) is a Brazilian graphic designer and illustrator.

Everaldo's works include general illustrations, comics, children's books, corporate design and many other areas.

Everaldo worked for Conectiva and LindowsOS, and later as a freelance artist for SUSE, KDE, Mozilla and many other Linux-related projects.

Not understanding much about operating systems at the time, he searched the Internet for an OS to install on his new machine, coming across Linux.

[6] Everaldo's signature style is the distinctive "crystal" look, mainly consisting of icons that appear to be made of highly reflective surfaces.

This inspired him to focus on an intermediate concept of icons, "between realism of Mac OS X and cartoon colored style of XP".
