Create a simple application for decoding resistor color codes.

Resistors are electronic components that oppose the flow of electricity and the resistance is measured in ohms. Color "bands" are used to indicate the value of resistance where each color signifies a number.

To complete this task you should have knowledge of resistor color codes.

You can use python GUI tools like Tkinter or wxPython.  In the application one should be able to select each of the colors of the FOUR bands and the resistor value and tolerance should be  displayed.
