Why are people being so autistic over colors today?
Toriyama doesn't give a shit, he colors things in the way he feels best compliment the illustration he's working on, along with lots of colors just changing over the years and being influenced by anyone who isn't Toriyama working on them
Hell, like
>>6998193 pointed out, Frieza's green in that illustration but he's also been pure white, grey and even blue over the years
For what it's worth, Nappa's armor was at some point colored the same as Radditz's like pic related shows but the yellow armor became much more common and "correct"
Next we'll be arguing over Cell's proper shade of green or Buu's correct bubblegum pink...
