Happy New Year!
Glad to hear you like it :)
Check
http://kodi.wiki/view/Official:Trademark_Policy_index
-> Media Center Logos, and
-> Visual Identity Guidelines:
"Our logos are to be displayed in its entirety on either a solid light or dark background (avoid mid-tone or strongly colored backgrounds)."
So no choice for white or black necessary ;)
I completely agree about the font, it's just a temporary lazy indication where the wordmark would come (as i.e. the app icon would be displayed on Android).
I'll try to complete the logo with a better matching font soon.
PS. is there a place I can upload the stuff?
