Name That Color And Hue with I18n
Convert hexadecimal, RGB, HSL, LCH or CMYK color to a name and a shade with i18n support.
ntc-hi-js is a complete overhaul of Chirag Mehta and Colblindor work.
ntc-hi-js leverage the powerful chroma.js library to support a wider range of formats and offer more accurate matching.
Installation
Install directly:
npm i ntc-hi-js
Or add to your package.json
"ntc-hi-js": "^3.2.0"
Getting Started
const ntc = require('ntc-hi-js')
const n_match = ntc.name('#6195ED', 'en')
n_match.color.hex // This is the RGB value of the closest matching color
n_match.color.name // This is the text string for the name of the match
n_match.color.exact // True if exact color match, False if close-match
n_match.shade.hex // This is the RGB value for the name of colors shade
n_match.shade.name // This is the text string for the name of colors shade
n_match.shade.exact // True if exact color match, False if close-match
console.log(n_match) // [ '#6495ED', 'Cornflower Blue', false ]
Usage
Supported Formats
ntc-hi.js leverage the powerful chroma.js library to support a variety of formats. Any color information that fit into a single variable can be used directly:
ntc.name('619') // hex
ntc.name('#619') // hex
ntc.name('6195ED') // hex
ntc.name('#6195ED') // hex
ntc.name(0xff3399) // hex
ntc.name(16777215) // int
ntc.name([97, 149, 237]) // rgb
ntc.name({ r:97, g:149, g:237}) // rgb
ntc.name({ h:120, s:1, l:0.75}) // hsl
ntc.name({ l:80, c:25, h:200 }) // lch
ntc.name({ c:1, m:0.5, y:0, k:0.2}) // cmyk
If none of these format is satisfactory, it's also possible to directly pass a chroma.js color object. Please refer to their documentation for further information.
ntc.name(chroma(330, 1, 0.6, 'hsl'))
Translate into a target locale
Retrieving a translation is a simple parameter with the locale code.
ntc.name('#6195ED', 'fr')
If a locale table is not present, the fallback locale will be used. To change this fallback:
ntc.fallback_locale = 'en' // 'en' is the default fallback
Add your own color dictionary
A color dictionary is structured as a folder with a json object for each locale.
├── my_dictionary
│ ├── en.json
│ ├── fr.json
│ └── ...
The json object for a locale is a list of hex/name combos.
[
["FF0000", "Red"],
["FFA500", "Orange"],
["FFFF00", "Yellow"],
["008000", "Green"]
]
Once this is setup, you must register your dictionary path and launch a rebuild. The example also include the usage of a absolute path, which might be handy for moving the object around modules.
// with a relative path
ntc.dictionaries_path.my_dictionary = './my_dictionary'
// with an absolute path
ntc.dictionaries_path.my_dictionary = require('path').resolve('my_dictionary')
ntc.build_dictionaries()

To-Do
- Support more locales
- Review current locale for the quality of some translations
