What is false color image?

A false color image is a visual representation where colors are assigned to different wavelengths of light that are not typically represented in natural colors. This technique is often used in satellite imagery and scientific imaging to highlight specific features or anomalies, such as vegetation health or mineral composition. By using non-visible wavelengths, like infrared, false color images can reveal information that is not perceptible to the human eye, aiding in analysis and interpretation.
