The colour of Naruto‘s Rasengan


In the anime it's clearly said, that every one sees the chakra of the Nine-
Tailed Fox as red/orange, when Naruto uses it. But no matter what chakra
Naruto uses for his Rasengan, it's always blue (like normal). Why is this?




Naruto's _own_ chakra color is blue, which contrasts with the Nine-Tails' own
chakra color of red.

Interestingly though, despite Naruto using the Nine-Tails' chakra to create
larger and larger Rasengan, the color remains the same. This might be a plot
hole; this may be indicative of Naruto himself performing the attack with a
larger amount of chakra under his control.
