Should icons change with themes?

[Thomasrope]

I'm fairly new to theming, so I'm curious... When you download and apply a new theme, should icons also change as shown on the theme site. I downloaded a new theme today but my icons didn't change. I read that some icons are not compatible with Nova Prime.

Depends on the phone/launcher you're using and if the theme contains all the elements or if you need to download a set (wallpaper, icons, theme).
