Colors can be represented in a computer using an RGB color scheme, where each color is a combination of red, green, and blue components. In $24-$bit RGB$,$ each component uses $8$ bits, from a low of $(00000000)2$ to a high of $(11111111)2.$ This translates to a range of $0-255$ in base $10.$ The $8$ bits of red are stored first, followed by the $8$ bits of green, and finally the $8$ bits of blue.
