In pixels that can display 2-bit color, meaning there are 2 statements "Yes" and 2 claims "No", then the number of colors can be displayed 2 bits x 2 = 4 color statement. Pixel is capable of displaying a 3-bit means 2 x 2 x 2 = 8 colors, 4 bits means 2 x 2 x 2 x 2 = 24 = 16 colors and can be concluded that seterusnya.Jadi bit pixel depth is the capability of storing bits or information, in this will affect the number of colors that can be displayed.
