56 Ω resistor colour code
Four bands: Green · Blue · Black · Gold. The first two give the digits, the third multiplies, the fourth states how far off the real part may be.
Nominal

56 ohms
Real range at ±5%
53.2 Ω – 58.8 Ω
A gold band allows this much drift.

Band by band
| Band | Colour | Meaning |
|---|---|---|
| 1 | Green | 1st digit — 5 |
| 2 | Blue | 2nd digit — 6 |
| 3 | Black | Multiplier — ×1 |
| 4 | Gold | Tolerance — ±5% |
The same value on a five-band part
Precision resistors carry three significant digits instead of two, so the same 56 Ω looks different.
