Using a fez (or fes, if you prefer) as a logo for a "Fast, Effective, Simple" framework named "Kemal" is kind of unfortunate/ironic. Kemal Ataturk actually abolished the use of the fez [1].
So, even though Atatürk was not the first person to be named Kemal, he practically "owns" the name today.
It was mainstream even before Ataturk in India/Iran (Fars territory). https://en.wikipedia.org/wiki/Ibn_Kemal
