Electronic Resistor Color Codes

Part of the Electronics All-in-One For Dummies Cheat Sheet

Resistor values are marked with small colored stripes. The first two stripes represent numeric values and the third stripe is a multiplier. The fourth stripe gives you the resistor’s tolerance — that is, it tells you how close to the indicated value you can expect the resistance to actually be.

For example, a resistor with brown, black, orange, and gold stripes is a 10,000 whose actual resistance may vary by as much as 10%.

Color Digit Multiplier (in Ohms) Tolerance
Black 0 1 20%
Brown 1 10 1%
Red 2 100 2%
Orange 3 1 k 3%
Yellow 4 10 k 4%
Green 5 100 k
Blue 6 1 M
Violet 7 10 M
Gray 8 100 M
White 9 1,000 M
Gold 0.1 5%
Silver 0.01 10%
