How Resistor Color Codes Work

Color Code System

Resistor color codes use colored bands to indicate the resistance value and tolerance. Most common resistors use a 4-band system where each color represents a specific digit or multiplier.

4-Band System:

  • Band 1: First significant digit
  • Band 2: Second significant digit
  • Band 3: Multiplier (number of zeros)
  • Band 4: Tolerance

Color Reference

Black = 0
Brown = 1
Red = 2
Orange = 3
Yellow = 4
Green = 5

Frequently Asked Questions

How do I read resistor color codes?

To read resistor color codes, start from the band closest to one end. The first two bands represent significant digits, the third band is the multiplier, and the fourth band indicates tolerance. Use our converter tool to easily translate values to color sequences.

What is the difference between 4-band and 5-band resistors?

4-band resistors have two significant digits, while 5-band resistors have three significant digits, making them more precise. 5-band resistors typically have tighter tolerances and are used in precision applications where exact resistance values are critical.
