Not entirely true. The three OG normal releases were manga. Then Vegeta as the infamous web exclusive start had shaded hair, the line was dying so they probably tries to appeal to the west, but his colouring still was pretty bright. Well, that worked, because Trunks got chosen as the next release. They continued the shaded hair. Then ssj3 Goku came, shading overboard.
THEN the line started taking off in 2012, but Vegeta, Frieza, norm Goku, the Twins and 16 are all either manga or NEUTRAL. Frieza looks the same, the twins look the same in anime and manga.
When it comes down to it there's vegeta who's kinda semi-anime, Trunks who's anime, and ssj3 goku. [EDIT: forgot krillin, ownedcount +1] Every other clear anime release was a repaint exclusive.
And every other release was either neutral because it ,looked the same, or manga. And then there's Broly, who was made pretty much because of us, like Trunks.
That puts 3,5-4 non-repaint anime releases, to, counting vegetto, now five manga releases.
Clearly this line has switched back at the turning point of it taking off. Vegetto put the nail in the coffin, this line's "normal" releases are manga releases unless it's something like Broly which exists solely because of the west.
EDIT: oh yeah and then there's krillin with his white eyes and dark gi. I don't think anyone gets what the **** happened there.
But regardless, by now, I think Vegetto signals they've gone back for anything that's of interest to japan. Which is nearly everything.
