Black 0 Brown 1 Red 2 Orange 3 Yellow 4 Green 5 Blue 6 Purple 7 Gray 8 White 9 Gold and Silver indicate the error
The meaning of each color ring is as follows:
- The first color ring: the first digit of the resistance value.
- The second color ring: the second digit of the resistance value.
- The third color ring: the power of 10.
- The fourth color ring: error indication.
