Are the the colorings in the official shonen jump chapters not canon?

[Zavage10]

I ask this , because current naruto and sasuke look far different on the latest manga volume cover (drawn and colored by kishi) when compared to the offical shonen jump colored chapters. If that's the case would it be safe to assume that Rikudou Madara's color scheme is the same as Rikudou Obito's all white appearance?

 

[The Necromancer]

Kishi's colorings are cannon for now until portrayed in the anime.

 

[Sonzumaki]

The shonen cover + Manga cover > colored chapter.
We know Sasuke's rinnegan is purple and Naruto's transformation doesn't affect his skin, but we can't be too sure about Madara's colors...

I prefer Sasuke having purple Rinnegan and Naruto with regular coloured skin anyway.

Kishi probably changed his mind and decided to recolour. And I'm happy with his decision.

I just hope Kakashi's Susanoo really isn't gold/oorange - that should be Itachis colour. Kakashi should really have a grey/silver Susanoo.
