After recently thinking, the color red in Naruto seems to be associated with power. Why do I think this? Akatsuki cloaks have red clouds, the sharengan is red, when Naruto goes kyuubi he gets red chakra.
So what do you all think, do you think the mangaka associates being really powerful with the color red?
Also, if we want to make this thread a little more useful, what otther color similarlities have others noticed in Naruto? Things that seem to be ongoing themes?
