Which factor does NOT influence radio wave propagation?

Propagation of radio waves is shaped by the environment and atmospheric conditions that the signal traverses. Weather can cause attenuation or scattering (rain fade, humidity effects), geographic location determines terrain, surface conductivities, and obstacles the signal must pass over or around, and time of day changes the ionospheric conditions that affect long‑distance propagation, especially for lower frequencies. Transmitter color, on the other hand, has no impact on any physical property of the radio waves, such as frequency, power, antenna behavior, or how the atmosphere and terrain influence the signal. It’s simply a visual attribute with no effect on propagation.
