Capacitor Color Codes

Color      Significant     Decimal            Tolerance           Temp.
            Figure         Multiplier     >10pF       <10PF       coeff.
Black         0               1         +/-20%      +/-2.0pF       -0
Brown         1              10         +/-1%                      -30
Red           2             100         +/-2%                      -80
Orange        3            1000                                    -150
Yellow        4                                                    -220      
Green         5                         +/-5%       +/-0.5pF       -330
Blue          6                                                    -470
Violet        7                                                    -750
Gray          8               0.01                  +/-0.25pF       30
White         9               0.1       +/-10%      +/-1.0pF        500

The 1st significant, 2nd significant figures as well as the multiplier follow the standard color code for capacitors.

Voltage              Tolerance
Brown  = 100                 Black   =+/-20%
Red    = 250                 White   =+/-10%
Yellow = 400                 Green   =+/-5%

The value of some capacitors like aluminum and glass are usually written on the component. Other information like operating voltage is also stamped on the component.
