What is the maximum number of A color image uses 16 bits to represent a pixel?

A color image that uses 16 bits to represent a pixel typically divides the bits among the color channels. A common configuration is 5 bits for red, 5 bits for green, and 6 bits for blue (RGB565 format). This allows for a maximum of 65,536 unique colors in the image, as each pixel can represent one of those colors. Thus, the maximum number of distinct colors that a 16-bit image can represent is 65,536.
