Color Ring Resistor Calculator

The color ring resistance calculator version 1.0 that a netizen spent about 6 hours making is simple and clear.
A color ring resistor is a color ring of a certain color painted on the resistor package (i.e., the surface of the resistor) to represent the resistance value of the resistor.
The first three rings are the value of the resistor, with 10 colors of black, brown, red, orange, yellow, green, blue, purple, gray and white representing the ten numbers from 0 to 9. The fourth ring is the multiplier, with 12 colors of black, brown, red, orange, yellow, green, blue, purple, gray, white, gold and silver. The colors represent 1, 10, 10², 10³ all the way up to White represents 10 to the 9th power, gold is 10 to the -1 power, silver is 10 to the -2 power, and the fifth ring is the error. Commonly used ones include silver (±10%), gold (±5%), and red (± 2%) brown (±1%) green (±0.5%) five colors.
For example: green, blue, black, red is 560*100=56000Ω=56KΩ, the error is ±2%
Green, blue, black, silver and green are 560*0.01=5.6Ω, error ±0.5%
