Resistor Colour Tool

This tool will help you identify the value of your resistor.

Look for these cues to find the correct reading direction:

The Spacing: The tolerance band (often gold or silver) is usually separated by a wider gap from the other bands.
The Colour: Gold and silver are **only** used for the multiplier and tolerance bands, not for the first significant digits.
