Colour code for fixed resistors:
| Colour | Significant Figures | Multiplier | Tolerance |
| Silver | 10-2 | +- 10% | |
| Gold | 10-1 | +- 5% | |
| Black | 0 | 1 | |
| Brown | 1 | 10 | +- 1% |
| Red | 2 | 102 | +- 2% |
| Orange | 3 | 103 | |
| Yellow | 4 | 104 | |
| Green | 5 | 105 | +- 0.5% |
| Blue | 6 | 106 | +- 0.25% |
| Violet | 7 | 107 | +- 0.1% |
| Grey | 8 | 108 | |
| White | 9 | 109 | |
| None | +- 20% |
Four Band Fixed Resistor
Two first bands (first band is the one nearest the end of the resistor) indicates the value, the third indicates the multiplier and the fourth indicates tolerance.
Example - Value Four Band Fixed Resistor
A resistor with the four colour bands
yellow - violet - orange - red
has a value of 47 kΩ with tolerance +- 2%.
Five Band Fixed Resistor
Three first bands (first band is the one nearest the end of the resistor) indicates the value, the fourth indicates the multiplier and the fifth indicates tolerance.
Example - Value Five Band Fixed Resistor
A resistor with the five colour bands
red - yellow - white - orange - brown
has a value of 249 kΩ with tolerance +- 1%.
