Then I thought about it and I remember when Naruto came and confronted Madara he was in sage mode but no pigmentation or chakra cloak. Considering that at that point, he had 5 different energies inside of him, it probably took a moment for him to adapt. (energies being: Spiritual, Physical, Natural, Kurama and Hagoromo). Considering that Naruto couldn't synchronize Sage and Kurama mode until Kurama allowed it, it may also be a case of Kurama needing to adapt to the energies.

I think it's clear that he owes Six Paths Sage Mode to Hagoromo and that the power of the tailed beasts was just extra help. Furthermore, it's likely that he used up all of Hagoromo's chakra like Sasuke, and like Sasuke has remnant powers (e.g. Sasuke's Rinnegan). Naruto's remnant power being a powerful Kurama Sage Mode.
