How would I go about changing the colour of the auras and chargeup auras? Because if I could, I would.
Besides, the auras changed after the fight between Goku and Frieza, because the quality if the images changed as well. Goku still had his red aura from Kaio Ken, but no-one had a different coloured aura. Look at the difference between the auras when Goku fought Captain Ginyu, and when he fought Frieza as a SSJ. In the ginyu one, Ginyu had a purple outline around his aura. In the fight between Goku and Frieza, Frieza had an aura of purple. In the 100% Frieza vs SSJ Goku, Freiza had a blue aura, for 1 episode, then evryone either had a gold aura, or a white aura from every episode up to the Buu Saga, where Buu had a Pink aura in all his pure stages.(Fat Buu, Evil Buu, Buu, and Kid Buu) But then Uub had a pink aura and a white aura.
