Why do Trunks have purple hair?

Trunks, the son of Vegeta and Bulma, has purple hair because of the combination of his parents' traits. While Vegeta has black hair, Bulma has blue hair, leading to a unique blend of both their characteristics in Trunks. The purple hair can be seen as a result of this mix, where the colors combine to create a hue that's a bit different from either of his parents' hair colors.

The Explanation Behind Trunks' Hair Color:

• Vegeta's Genetics: As a Saiyan, Vegeta's hair color is traditionally black, and this is passed down to Trunks.
• Bulma's Influence: Bulma, being a human with blue hair, influences Trunks' appearance as well. While the color may not be an exact mix of blue and black, the result is often shown as a purple hue in the anime and manga, likely due to the blending of both parents' genes.

Why Purple Hair?

In anime and manga, sometimes hair colors do not always align with reality. Purple is often a stylistic choice to reflect both Vegeta's strong, bold Saiyan lineage and Bulma's distinct blue hair. The purple hair also makes Trunks visually stand out among other characters, giving him a unique and memorable appearance that differentiates him from both of his parents.

Different Versions of Trunks' Hair:

• Dragon Ball Z: Trunks’ hair is typically shown as a light purple in the anime.
• Dragon Ball Super: The hair color remains purple, but with slightly varying shades depending on the art style and animation.
• Alternate Timeline (Future Trunks): In the future timeline, Future Trunks' hair color remains consistent with his present-day counterpart, appearing purple.

Conclusion:

Trunks has purple hair due to the combination of his Vegeta's black Saiyan hair and Bulma's blue hair, creating a unique and distinctive shade. The purple hair is a visually striking and memorable feature that makes Trunks one of the most recognizable characters in the Dragon Ball series.
