This app is a calculator that provides resistance color codes and combinations
One of the functions of this application is to enter the color code of the resistor you are using, it will calculate and provide you the resistance and tolerance of the resistor
Another function of this application is the resistor combination calculator and color code calculator. Enter the required resistance and it will provide you with all combinations of 2 standard resistances in a particular series. If combined in series or parallel, the equivalent resistance will be 2.5 of the desired value. Then you can click on each combination and it will display its color code, you can enter the standard resistance and immediately view its color code.
