my guess is that in the manga, they wanted her to have purple hair, and when they looked at it in the anime, they decided that blue might be better to go with. that is my opinion. i have been curious about that too.

Hhmm,I thought so, but I've never found a real explanation. Why did the animators change her hair color? Moreover,it would make もっと見る sense as to why Trunks has purple hair.
I have some pages in the マンガ colored によって Toriyama and I can say that there are many Colors（色） that do not match the anime, probably the TOEI アニメーション had decided to change them because with the original colours the アニメ would have an older look. For example nam have a ピンク dress in マンガ :)

Yeah indeed in some coloured pages Bulma has purple hair, then blue または gray, even red..! but in the illustations she has (almost) always purple hair. It's strange!
