150 Ω resistor colour code

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

142.5 Ω – 157.5 Ω

A gold band allows this much drift.

Band by band

Band	Colour	Meaning
1	Brown	1st digit — 1
2	Green	2nd digit — 5
3	Brown	Multiplier — ×10
4	Gold	Tolerance — ±5%

The same value on a five-band part

Precision resistors carry three significant digits instead of two, so the same 150 Ω looks different.
