If Naruto had an OUNCE of blue (normal) chakra in him, then why is it that he has Red Kyuubi chakra pouring out of every chakra opening? He's got control of his actions, but that has nothing to do with the chakra he uses. Especially now that he's become even more taken over by the nine tails, it doesn't make any sense that he would use blue chakra...
