Resistor Color Code

Most resistors have three, four or five color bands. The first band is the one closest to the end of the resistor body.

Color Band Number
1 2 3 4 5
3 Bands Digit Digit Multiplier ** None
4 Bands Digit Digit Multiplier Tolerance None
5 Bands Digit Digit Digit Multiplier Tolerance
** All 3 band resistors are 20% tolerance.

Color Digit Multiplier Tolerance

Black 0 1 +/- 20
Brown 1 10 +/- 1
Red 2 100 +/- 2
Orange 3 1,000 +/- 3
Yellow 4 10,000 +/- 4
Green 5 100,000 -
Blue 6 1,000,000 -
Violet 7 10,000,000 -
Gray 8 100,000,000 -
White 9 -
Gold - 0.1 +/- 5
Silver - 0.01 +/- 10
No Color - +/- 20
