Color images, several colors

Quick answer：

Color images refer to photographs or digital images that contain a wide range of colors. The term 'several colors' suggests that the image has more than just a few hues, indicating a more vibrant and detailed visual representation. This can be achieved through various color models used in image processing and photography, such as RGB (Red, Green, Blue) or CMYK (Cyan, Magenta, Yellow, Key/Black).
