Capacitor color coding is less common than resistor color coding, but it does exist, especially for some older or smaller capacitors, like ceramic disc capacitors. Here's how the capacitor color code works:
Capacitor Color Code Table
Color Codes
•Black- 0 - x1 pF
•Brown- 1 - x10 pF

•Orange- 3 - x1 nF
•Yellow- 4 - x10 nF
•Green- 5 - x100 nF
•Blue- 6 - x1 µF
•Violet- 7 - x10 µF
•Gray- 8
•White- 9
•Multiplier:
•Black- x1 pF
•Brown- x10 pF

•White- ±10%
Voltage Rating(For some capacitors)
•Black- 4V
•Brown- 6V
•Red- 10V
•Orange- 16V
•Yellow- 25V
•Green- 40V
•Blue- 63V
•Violet- 100V
•Gray- 250V
•White- 400V
•Gold- 630V
•Silver- 1,000V
For capacitors that utilize color codes
•The first color band indicates the first digit.
•The second color band indicates the second digit.
•The third band provides the multiplier.
•The fourth band (if present) shows the tolerance.
•Sometimes, there's an additional band or a dot to indicate the voltage rating.
It's important to mention that many capacitors, especially larger ones or those with higher capacitance values, will have their values written directly on them in a numerical format instead of using color codes. It's always a good idea to consult the data-sheet or documentation associated with a particular capacitor if there's any doubt.
