In his one-tailed form, Naruto uses the Nine-Tailed Demon Fox's chakra shield to spin the chakra while using his own hand as a shell to form a Rasengan. In anime, the Demon Fox Rasengan took a more purplish color rather than the standard blue. In the second movie and video games, the Rasengan took a reddish color, similar to the demon fox's chakra. When Naruto fights Sasuke Uchiha at the Valley of the End, they end the battle with a Flapping Chidori and a Demon Fox Rasengan. The Demon Fox Rasengan is more powerful and seems to be larger than the normal Rasengan, due to the demon fox's chakra.
