             Each pixel holds a numeric value, known as a pixel value, reflecting attributes like color or brightness. In remote sensing, pixel values encode information about the observed scene, 
             facilitating data interpretation and analysis. These values are fundamental for understanding and processing digital imagery.

             Human vision perceives color through detecting the entire visible spectrum, and our brains process this information into distinct colors. In contrast, many sensors work by capturing 
             information within narrow wavelength ranges, storing it in channels or bands. Digital representation involves combining and displaying these channels using primary colors
