What is the difference between 8-bit and 24-bit?
QUOTE said:
Color depth is a computer graphics term describing the number of bits used to represent the color of a single pixel in a bitmapped image or video frame buffer. This concept is also known as bits per pixel (bpp), particularly when specified along with the number of bits used. Higher color depth gives a broader range of distinct colors.

24-bit Truecolor uses 8 bits to represent red, 8 bits to represent blue, and 8 bits to represent green. 28 = 256 levels of each of these three colors can therefore be combined to give a total of 16,777,216 mixed colors (256 x 256 x 256). Twenty-four-bit color is referred to as "millions of colors" on Macintosh systems.
