Resistance color code decoder function:

Decoding color of the bands into resistance value (it is answer on "what the resistance with the colors brown-black-red-gold?" and the like): select a number of color bands, choose a color to each of them. Under the resistance image the result will be displayed in the form X*10Y Ohm . In the field "RESULT" the same result will be displayed in the form of Ohm, kOhm or MOhm.

Encoding resistance value to color (it is answer on "what the 10k resistor color code?" and the like):  select range (Ohm, kOhm, Mohm) from drop-down menu, type value in RESULT field of decoder (digit only, e.g. 123, 12.3, 1.23, 0.123),  choose tolerance. Number and color of bands on the resistor image will be recalculated accordingly.
