Why three channels?

All three views image the identical scene at the identical instant — only the wavelength band differs.

Visible — reflected sunlight only. Cloud shape and brightness, nothing about temperature or moisture.
Infrared — emitted heat. Colder tops (taller, more violent storms) read differently from warm low cloud, even when both look like plain white blobs in Visible.
Water Vapor — mid/upper-tropospheric humidity. Shows moisture plumes over totally clear sky, where Visible and Infrared show nothing at all.
