This graphical calculator works both ways- you can get resistor values from color codes or generate color codes from resistor values (5%, 10% and 20% tolerance).

Note that only certain "standard" electronic component values specified by Electronic Industries Association (EIA) and IEC publication 60063 may actually be available. See a complete Standard Decade Resistor Values table. Resistors may have different number of color bands depending on the tolerance. The same color scheme is used for capacitors (in picofarads pF) and inductors (in microhenries µH).
