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

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.
