Obata has some of the best draftsmanship skills in comics, besides have a clean, detailed "manga" style with crossover appeal. He worked on the popular Deathnote series and everything that I get to see by him has the same impeccable skill level.
Shonen Jump is a mostly black and white anthology title numbering roughly 384 pages of manga comics. A few comics get color for a few pages. This is a practice also that occurs in some European comic titles. This has more to do with printing setups that makes color available for only a few pages, versus some grand scheme of limited color.
