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

6.8 ohms
Real range at ±5%
6.46 Ω – 7.14 Ω
A gold band allows this much drift.

Band by band
| Band | Colour | Meaning |
|---|---|---|
| 1 | Blue | 1st digit — 6 |
| 2 | Grey | 2nd digit — 8 |
| 3 | Gold | Multiplier — ×0.1 |
| 4 | Gold | Tolerance — ±5% |
The same value on a five-band part
Precision resistors carry three significant digits instead of two, so the same 6.8 Ω looks different.
