Four Bands

1.5 kΩ resistor colour code

Four bands: Brown · Green · Red · Gold. The first two give the digits, the third multiplies, the fourth states how far off the real part may be.

1,500 ohms

Real range at ±5%

1.425 kΩ – 1.575 kΩ

A gold band allows this much drift.

The same value on a five-band part

Precision resistors carry three significant digits instead of two, so the same 1.5 kΩ looks different.
