The factor that has the least impact on a bullet's travel through the air is bullet color. While the color of a bullet might affect its visibility or concealment in certain environments, it does not significantly influence its performance in terms of trajectory, range, or stability during flight. The physical and aerodynamic properties of the bullet, such as its shape, mass, and caliber, play a much more crucial role in determining how it travels through the air.

In contrast, other factors like air density, wind speed, and temperature have substantive effects on bullet travel. Air density affects the amount of drag a bullet experiences; higher density leads to more drag, which slows the bullet down. Wind speed can alter the bullet's path significantly, especially over long distances, as it can push the bullet off course. Temperature influences air density as well; warmer temperatures result in lower air density, allowing the bullet to maintain higher velocities for longer distances. These elements are critical for accurate shooting and understanding ballistics, contrasting with the minimal role of bullet color.
