Color of Gluon Jets in Electron-Positron Annihilation

[appearelectro]

What is the color of gluon (or gluon jets) predicted according to QCD?

Here, I am talking about electron-positron annihilation that may cause gluon jets.

Good question, and likewise: what color is a quark jet?

Answer: Must be colorless. When a high energy parton is created in a collision, the jet we see consists of the bremsstrahlung produced by the parton, not the parton itself.
