Four colored rings are used to indicate the resistance value at a fixed resistor. These rings are placed close together at one end of the resistor body. Color of each ring defines a number. See the figure bellow



This color code read from the end nearest resistor, we can know that these colors have meaning:
- The first ring, the first digit of the value of resistance
- The second ring, the second digit of the value of resistance
- The third ring, a multiplier factor (a rank value of 10, or the number of zeros behind the first two digits)
- The fourth ring, is the tolerance of the value of resistance

The table below shows the meaning of the colors on the resistor body
