I have to do some themes for this mobile app I am designing, the problems is after I sent the first preview of the themes to the client he came back saying that he wants different icons for each theme... which I find a little awkward I just don't know if it is or not, or how to explain to him about this. Right know the only thing that is different at the icons between themes is the style(color + effects(drop shadow etc)).
Shouldn't the icons always be the same, only different in style? Just so you don't create confusion in the user's mind just by switching a theme...
Themes I have to do are like : Apple menu style, Windows Mobile Style, Facebook path menu style etc...
EDIT:
OK. After reading your comments and answers I think that the app will be cross platform, so it needs to resemble stuff in the Operating System of the device(OS,Windows Mobile, Android).
But it is kind of weird cause I only have iOS and Windows Mobile, no android, an these 2 mentioned earlier came in a list of other themes like :Retro look, Facebook look, Classic paper so... i think it was a matter of bad communication between the client and me...
From what I get from you answers if it is cross platform its better to stick to the device Operating System "Defaults" not so much in term of look but more in layout and such things, and make sure to use the "native" stuff that comes with an app on those different devices... this is gonna be a long one, need to do some more research...:)
