Plain color conversion functions
npm install color-convertColor-convert is a color conversion library for JavaScript and node.
It converts all ways between rgb, hsl, hsv, hwb, cmyk, ansi, ansi16, hex strings, and CSS keywords (will round to closest):
``js
import convert from 'color-convert';
convert.rgb.hsl(140, 200, 100); // [96, 48, 59]
convert.keyword.rgb('blue'); // [0, 0, 255]
const rgbChannels = convert.rgb.channels; // 3
const cmykChannels = convert.cmyk.channels; // 4
const ansiChannels = convert.ansi16.channels; // 1
`
`sh`
npm install color-convert
Simply get the property of the _from_ and _to_ conversion that you're looking for.
All functions have a rounded and unrounded variant. By default, return values are rounded. To get the unrounded (raw) results, simply tack on .raw to the function.
All 'from' functions have a hidden property called .channels that indicates the number of channels the function expects (not including alpha).
`js
import convert from 'color-convert';
// Hex to LAB
convert.hex.lab('DEADBF'); // [ 76, 21, -2 ]
convert.hex.lab.raw('DEADBF'); // [ 75.56213190997677, 20.653827952644754, -2.290532499330533 ]
// RGB to CMYK
convert.rgb.cmyk(167, 255, 4); // [ 35, 0, 98, 0 ]
convert.rgb.cmyk.raw(167, 255, 4); // [ 34.509803921568626, 0, 98.43137254901961, 0 ]
`
Note that this does not apply to functions that convert from a color that only requires one value (e.g. keyword, ansi256, hex, etc.)
`js
import convert from 'color-convert';
convert.rgb.hex(123, 45, 67); // '7B2D43'
convert.rgb.hex([123, 45, 67]); // '7B2D43'
`
Conversions that don't have an _explicitly_ defined conversion (in conversions.js), but can be converted by means of sub-conversions (e.g. XYZ -> RGB -> CMYK), are automatically routed together. This allows just about any color model supported by color-convert to be converted to any other model, so long as a sub-conversion path exists. This is also true for conversions requiring more than one step in between (e.g. LCH -> LAB -> XYZ -> RGB -> Hex).
Keep in mind that extensive conversions _may_ result in a loss of precision, and exist only to be complete. For a list of "direct" (single-step) conversions, see conversions.js.
