I didn't see them as a figure of speech, they are a figure of speech. Naruto says "if I had to put it in colours". Not "my chakra is coloured yellow". He could've said "if I had to put it in numbers, my chakra would be 7 and the other chakra would be 9". He said it metaphorically, not literally.

And yes, I know that his Rasengan has been coloured yellow and his fox cloak red. But the Rasengan has also been coloured blue and normal chakra is often depicted as blue. But then again, A's lightning armour is blue as well, despite being lightning chakra, which - if we go by logic - should be yellow. And you know what else is yellow? Naruto's chakra modes, despite using the fox chakra. Which is red.

You see? There's no logic behind the chakra colours and Naruto's statement was all but literal.
