The resistor color code is the scheme of coloured bands painted on a resistor to show its value, used because the parts are too small to print numbers on. Reading left to right, the first bands are significant digits, the next band is a power-of-ten multiplier and the last band is the tolerance. For a 4-band part the value is (10 × digit1 + digit2) × 10^multiplier ohms; 5- and 6-band parts add a third significant digit for tighter precision (and, on 6-band parts, a temperature-coefficient band). Each colour maps to a fixed number: black 0, brown 1, red 2, orange 3, yellow 4, green 5, blue 6, violet 7, grey 8, white 9, with gold and silver serving as ×0.1 and ×0.01 multipliers or ±5% and ±10% tolerances.
As a worked example, the classic brown-black-red-gold band pattern reads as digits 1 and 0, a ×100 multiplier and ±5% tolerance: (10 + 0) × 100 = 1,000 Ω, i.e. a 1 kΩ ±5% resistor whose true value lies anywhere from 950 Ω to 1,050 Ω. Decode any part by selecting the colour of each band from the drop-downs and the calculator returns the nominal resistance, the tolerance and the guaranteed value range.
Switch to reverse (encode) mode to go the other way: type a target resistance and the tool rounds it to the nearest value the digit bands can express, chooses the multiplier to match, and lists the band colours you would read off a real resistor of that value — handy when you have a schematic value and need to find or verify the physical part on your bench.

It rounds your target to the nearest value the digit bands can express, then chooses the multiplier so the reading matches — the same colours you would read off a real resistor of that value.
