Four Bands

3 MΩ resistor colour code

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

2.85 MΩ – 3.15 MΩ

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 3 MΩ looks different.
