Color code chart is a vital tool in the electronics field, serving as a bridge between visual information (the colored bands on the resistor) and key electrical parameters such as resistance value and tolerance. This chart typically present as a table or a series of color-coded samples, mapping each color to a specific digit, multiplier, or tolerance level. The chart generally includes the following key elements:
By mastering this colour code chart of resistor, electronics enthusiasts and professionals can confidently navigate the world of resistors, ensuring that their circuits perform optimally.
Basics of Resistor Color Codes
Color Bands
Resistors use color bands to indicate their resistance values. Each band represents a specific number or multiplier. You will typically find four, five, or six bands on a resistor. The first two bands indicate the significant digits of the resistance value. The 3 band resistor calculator acts as a multiplier, while the 4 band resistor color code calculator indicates tolerance. In some cases, additional bands may specify reliability or failure rates.
How to Read the Color Bands
To read the resistor color bands, you must start from the leftmost band. Identify the colors and match them to their corresponding numbers using a color code chart. For example, a resistor with red, purple, and yellow bands represents 27 followed by four zeros, which is equivalent to 270,000 ohms. This method allows you to quickly determine the resistance value without complex calculations.

For a 120 ohm resistor with a standard 4-band color code and a ±5% tolerance, the bands are brown, red, brown, gold.
Where are colour coded resistors commonly used?
Colored resistors are important in electronic devices and circuits. They are used in situations where precise resistance values are required, such as audio equipment, electronic products, industrial applications, automotive electronics, and communication systems.
What is the meaning of color coding?
Electronic product color coding uses color to indicate a specific value, attribute or category of a component, and is particularly useful for small components such as resistors, capacitors and inductors. Each color represents a number, multiplier or error, allowing component parameters to be quickly identified without printed text or symbols.
How to identify a 10K resistor?
When identifying 10K ohm resistors, we can rely on two different color coding schemes to determine their identity. For four-ring resistors, the color coding is “brown-black-orange-gold”, while five-ring resistors are color coded “brown-black-black-red-gold”. Both color codes point exactly to the 10K ohm resistor value.
How do I know which way to read a resistor?
When facing a resistor, place the color bands on the left and read them from left to right to find the resistance. For 5% or 10% tolerance resistors, the silver or gold band is on the right, but read all bands left to right. The first band on a resistor is never silver or gold.
What is resistor color coding?
Resistor color coding is a method of representing resistor resistance values and their errors by means of different colored rings on the resistor. Each color ring represents a specific number or multiplier, and by combining these color rings, we can derive the exact resistance value of the resistor.
