The serialization of the original comics began in 1999.
The first volume collection was released march 3, 2000.
Anime- was created in 2002. Manga- was published in 1997.
Naruto is manga.
Manga is the original Naruto/Naruto Shippuden source in which the anime comes from.
There is a manga for Naruto SD. See the related link for the online manga.
To fill in the gaps between the time each wave of manga volumes are published.
Currently, the Manga is still being published, and the Anime quite a bit behind the Manga. So there is no real way to tell when, or at what number the last chapter/episode will be.
Because the magazine it is published in comes out every Friday, and Masashi Kishimoto works with that deadline.
Naruto and Naruto Shippuden are also made into an anime as well as a manga.
No, Naruto is Manga
Naruto "colored manga" doesn't exist. Kishimoto draws the manga in black and white, with occasional colored pages to open chapters. There is colored animanga (manga made using colored snapshots of the animation) for the movies, but this is not the official Naruto manga. Also, all of the covers of the Naruto manga volumes are in color.
I am not sure what magma is, but i think you mean manga?? Manga is just the comic book version of it, Naruto started as a manga :]
Naruto shippuuden starts at chapter 245 in the Naruto Manga
