# Resistor Color

Welcome to Resistor Color on Exercism's PHP Track.

## Instructions
|
||
|
|
|
||
|
|
Resistors have color coded bands, where each color maps to a number. The first 2 bands of a resistor have a simple encoding scheme: each color maps to a single number.
|
||
|
|
|
||
|
|
These colors are encoded as follows:
|
||
|
|
|
||
|
|
- Black: 0
|
||
|
|
- Brown: 1
|
||
|
|
- Red: 2
|
||
|
|
- Orange: 3
|
||
|
|
- Yellow: 4
|
||
|
|
- Green: 5
|
||
|
|
- Blue: 6
|
||
|
|
- Violet: 7
|
||
|
|
- Grey: 8
|
||
|
|
- White: 9
|
||
|
|
|
||
|
|
Mnemonics map the colors to the numbers, that, when stored as an array, happen to map to their index in the array: Better Be Right Or Your Great Big Values Go Wrong.

More information on the color encoding of resistors can be found in the [Electronic color code Wikipedia article](https://en.wikipedia.org/wiki/Electronic_color_code)
