# NTC, but TS

Extracts the work of [ntc](https://chir.ag/projects/ntc/) - "Name That Color" - as a typescript library, with a few more features:

- caches colors already found, instead of looping through the array of available colors.
- extract color sets in different files for tree shaking, so developers can provide their own colors or use a set provided by the library.

## Live Demo of ntc

Try [Name that Color](https://chir.ag/projects/name-that-color/)!

## How to use

See the example below:

```ts
import { getColorName, initColors, ORIGINAL_COLORS } from "ntc-ts";

// First, init the available colors.
// By default, only the Black color is available
initColors(ORIGINAL_COLORS);

/*
// Returns a formatted color object FORMATTED_COLOR
type FORMATTED_COLOR = {
    exactMatch: boolean;
    name: string;
    rgb: string | null;
};
*/

const color01 = getColorName("#000");
// returns { exactMatch: true, name: 'Black', rgb: '#000000' }

const color01 = getColorName("#9399A7");
// returns { exactMatch: false, name: 'Manatee', rgb: '#9399A7' }

const color03 = getColorName("this is not a color");
// returns { exactMatch: false, name: 'not-a-color', rgb: null }

const color04 = getColorName(undefined);
// returns { exactMatch: false, name: 'not-a-color', rgb: null }
```

### Available color sets

There are 2 available color sets:

- `ORIGINAL_COLORS`, containing the original set provided by ntc.
- `MINIMAL_COLORS`, containing the original set trimmed down to a few main colors.
