All data is encoded in binary––1 (status of on) and 0 (off status). Color images are composed of group of color, with different amounts of red, green, and blue (ranging from zero to 255). Different values of these colors make up a single pixel. Thus, Image files contain millions of these color combinations. Each color channel is represented by eight bits. Eight bits = 1 byte. One color channel, red, green, or blue is represented by 8 bits or one byte. For example, blue is 01100110.
