The anime chose that different attacks of different characters somehow have various colors (Yellow Kienzan, Blue Kame Hame Ha, Purple Garlic Cannon...).
Shueisha decided that the color of ki must follow a logic that similar beings have similar energy, regardless of the way they use it, and it doesn't change color just because one character is not the same than the other. It is rather decided by the type of morphology and the kind of energy involved.
The Kame Hame Ha is just concentrated energy, so it is the same color than other characters concentrating energy in their own attacks or smaller "regular" blasts.
- All humanoids forms and some other races have golden ("yellow") ki.
- Alien morphologies like Piccolo and Freezer will often display purple ki (some of their attacks will use other schemes like red though and Nameks have been shown to use the gold "humanoid" form of energy for some regular blasts sometimes).
- "Overheat Mode" ki - as a result of the Kaioken - turns red, resulting in a red aura instead of the regular golden aura.
- Shared energy - like the Genki Dama and Namek's Great Elder "reveal your potential" move - is blue.
- The Super Saiyan energy turns white (is it somehow purified?) from what we've seen in the Freezer arc, but we don't know if it will be kept that way for upcoming arcs since panels of Super Saiyan 2 and Super Saiyan 3 show that the regular gold is back for those forms.
Note that even video games from the Super NES era like the
Super Butoden series and
Hyper Dimension, which used the manga colors even when there were only a few color pages back then, had already decided that the Kame Hame Ha should be yellow like regular blasts. In the end, it's only a bigger blast, not a different kind of energy. That's seemingly Shueisha's interpretation of it, at least.
Some people will prefer the anime version. As far as I'm concerned, blue is my favorite color, but I feel somehow more comfortable with Shueisha's interpretation of the colors for ki, and so the re-imagined golden Kame Hame Ha is my favorite version as a result.
