That still doesn't answer my question ^. I still want to know whether someone can use chakra whilst it's being absorbed. I'm pretty sure it can. Also one could speculate that when a tailed beast is inside a human, it differentiates in colour. As seen when Naruto was fighting for Kyubi's chakra. It was also blue. But when it touched Naruto's chakra and being, nearly corrupting him, it was red. So I think foreign chakra in that sort of sense is red.
