What is RGB in steganography?

In steganography, RGB refers to the color model used to represent images, where colors are defined by the intensities of red, green, and blue channels. Steganography techniques often manipulate the least significant bits (LSBs) of these RGB values to embed hidden information within an image without significantly altering its appearance. By modifying these bits, secret messages can be concealed within the image data, making it difficult for observers to detect the presence of hidden information. This approach leverages the human eye's insensitivity to subtle changes in color, allowing for effective data hiding.
