Javascript function to convert color names to hex codes

Question

Is there a built-in function that would convert a color by name into its hex representation? Like I want to pass 'white' and receive '#FFFFFF'. I really want to avoid coding all hundred if's myself :)

Answer 1

This will give it to you in RGB - you should be able to do the hex conversion pretty easily.

d = document.createElement("div"); d.style.color = "white"; document.body.appendChild(d) //Color in RGB  window.getComputedStyle(d).color 

Get Computed style is not supported on all browsers.

Answer 2

No, but using the list here you could create one. Something like this:

function colourNameToHex(colour) {     var colours = {"aliceblue":"#f0f8ff","antiquewhite":"#faebd7","aqua":"#00ffff","aquamarine":"#7fffd4","azure":"#f0ffff",     "beige":"#f5f5dc","bisque":"#ffe4c4","black":"#000000","blanchedalmond":"#ffebcd","blue":"#0000ff","blueviolet":"#8a2be2","brown":"#a52a2a","burlywood":"#deb887",     "cadetblue":"#5f9ea0","chartreuse":"#7fff00","chocolate":"#d2691e","coral":"#ff7f50","cornflowerblue":"#6495ed","cornsilk":"#fff8dc","crimson":"#dc143c","cyan":"#00ffff",     "darkblue":"#00008b","darkcyan":"#008b8b","darkgoldenrod":"#b8860b","darkgray":"#a9a9a9","darkgreen":"#006400","darkkhaki":"#bdb76b","darkmagenta":"#8b008b","darkolivegreen":"#556b2f",     "darkorange":"#ff8c00","darkorchid":"#9932cc","darkred":"#8b0000","darksalmon":"#e9967a","darkseagreen":"#8fbc8f","darkslateblue":"#483d8b","darkslategray":"#2f4f4f","darkturquoise":"#00ced1",     "darkviolet":"#9400d3","deeppink":"#ff1493","deepskyblue":"#00bfff","dimgray":"#696969","dodgerblue":"#1e90ff",     "firebrick":"#b22222","floralwhite":"#fffaf0","forestgreen":"#228b22","fuchsia":"#ff00ff",     "gainsboro":"#dcdcdc","ghostwhite":"#f8f8ff","gold":"#ffd700","goldenrod":"#daa520","gray":"#808080","green":"#008000","greenyellow":"#adff2f",     "honeydew":"#f0fff0","hotpink":"#ff69b4",     "indianred ":"#cd5c5c","indigo":"#4b0082","ivory":"#fffff0","khaki":"#f0e68c",     "lavender":"#e6e6fa","lavenderblush":"#fff0f5","lawngreen":"#7cfc00","lemonchiffon":"#fffacd","lightblue":"#add8e6","lightcoral":"#f08080","lightcyan":"#e0ffff","lightgoldenrodyellow":"#fafad2",     "lightgrey":"#d3d3d3","lightgreen":"#90ee90","lightpink":"#ffb6c1","lightsalmon":"#ffa07a","lightseagreen":"#20b2aa","lightskyblue":"#87cefa","lightslategray":"#778899","lightsteelblue":"#b0c4de",     "lightyellow":"#ffffe0","lime":"#00ff00","limegreen":"#32cd32","linen":"#faf0e6",     "magenta":"#ff00ff","maroon":"#800000","mediumaquamarine":"#66cdaa","mediumblue":"#0000cd","mediumorchid":"#ba55d3","mediumpurple":"#9370d8","mediumseagreen":"#3cb371","mediumslateblue":"#7b68ee",     "mediumspringgreen":"#00fa9a","mediumturquoise":"#48d1cc","mediumvioletred":"#c71585","midnightblue":"#191970","mintcream":"#f5fffa","mistyrose":"#ffe4e1","moccasin":"#ffe4b5",     "navajowhite":"#ffdead","navy":"#000080",     "oldlace":"#fdf5e6","olive":"#808000","olivedrab":"#6b8e23","orange":"#ffa500","orangered":"#ff4500","orchid":"#da70d6",     "palegoldenrod":"#eee8aa","palegreen":"#98fb98","paleturquoise":"#afeeee","palevioletred":"#d87093","papayawhip":"#ffefd5","peachpuff":"#ffdab9","peru":"#cd853f","pink":"#ffc0cb","plum":"#dda0dd","powderblue":"#b0e0e6","purple":"#800080",     "rebeccapurple":"#663399","red":"#ff0000","rosybrown":"#bc8f8f","royalblue":"#4169e1",     "saddlebrown":"#8b4513","salmon":"#fa8072","sandybrown":"#f4a460","seagreen":"#2e8b57","seashell":"#fff5ee","sienna":"#a0522d","silver":"#c0c0c0","skyblue":"#87ceeb","slateblue":"#6a5acd","slategray":"#708090","snow":"#fffafa","springgreen":"#00ff7f","steelblue":"#4682b4",     "tan":"#d2b48c","teal":"#008080","thistle":"#d8bfd8","tomato":"#ff6347","turquoise":"#40e0d0",     "violet":"#ee82ee",     "wheat":"#f5deb3","white":"#ffffff","whitesmoke":"#f5f5f5",     "yellow":"#ffff00","yellowgreen":"#9acd32"};      if (typeof colours[colour.toLowerCase()] != 'undefined')         return colours[colour.toLowerCase()];      return false; } 

Answer 3

@dlauzon suggested I convert my comment into an answer. Thanks for suggesting! Here it is :)

function standardize_color(str){
    var ctx = document.createElement('canvas').getContext('2d');
    ctx.fillStyle = str;
    return ctx.fillStyle;
}

function standardize_color(str){
    var ctx = document.createElement("canvas").getContext("2d");
    ctx.fillStyle = str;
    return ctx.fillStyle;
}

document.getElementById("myspan1").innerHTML = standardize_color("red");
document.getElementById("myspan2").innerHTML = standardize_color("PeachPuff");
document.getElementById("myspan3").innerHTML = standardize_color("PaleGoldenRod"); 
document.getElementById("myspan4").innerHTML = standardize_color("RGB(123,234,142)"); 
document.getElementById("myspan5").innerHTML = standardize_color("HSL(284,6%,49%)");

span { font-weight:800; }

The color named "Red" has a code of: <span id="myspan1">(requires js)</span>.<br>
 ...and color "PeachPuff"'s code is: <span id="myspan2">(requires js)</span>.<br>
 ...and "PaleGoldenRod" is: <span id="myspan3">(requires js)</span>.<br><br>
 
It works with "RGB(123,234,142)" too: <span id="myspan4">(needs js)</span>  
and therefore with: "HSL(284,6%,49%)", which is: <span id="myspan5">(requires js)
</span>.  Handy!

Answer 4

Edit: I've cleaned this up a bit and made a gist and demo of it. The basic approach remains the same.

The "add an element to the DOM and check its ComputedStyle" approach seems a little complex to me — you need to add it and check it and remember to remove it and you're changing the DOM just to compute a color and does it cause reflow? So here's a solution based on a temporary (and never rendered) <canvas>:

function colorToRGBA(color) {
    // Returns the color as an array of [r, g, b, a] -- all range from 0 - 255
    // color must be a valid canvas fillStyle. This will cover most anything
    // you'd want to use.
    // Examples:
    // colorToRGBA('red')  # [255, 0, 0, 255]
    // colorToRGBA('#f00') # [255, 0, 0, 255]
    var cvs, ctx;
    cvs = document.createElement('canvas');
    cvs.height = 1;
    cvs.width = 1;
    ctx = cvs.getContext('2d');
    ctx.fillStyle = color;
    ctx.fillRect(0, 0, 1, 1);
    return ctx.getImageData(0, 0, 1, 1).data;
}

function byteToHex(num) {
    // Turns a number (0-255) into a 2-character hex number (00-ff)
    return ('0'+num.toString(16)).slice(-2);
}

function colorToHex(color) {
    // Convert any CSS color to a hex representation
    // Examples:
    // colorToHex('red')            # '#ff0000'
    // colorToHex('rgb(255, 0, 0)') # '#ff0000'
    var rgba, hex;
    rgba = colorToRGBA(color);
    hex = [0,1,2].map(
        function(idx) { return byteToHex(rgba[idx]); }
        ).join('');
    return "#"+hex;
}

Note that this lets you use anything that's a valid canvas fillStyle, so if you want to gin up a 1 pixel pattern from an image, it'll tell you the color of that as well.

I've tested this in reasonably modern versions of IE, Chrome, Safari, and Firefox.

Answer 5

Here function where you use the browser to calculate it for you

function getHexColor(colorStr) {
    var a = document.createElement('div');
    a.style.color = colorStr;
    var colors = window.getComputedStyle( document.body.appendChild(a) ).color.match(/\d+/g).map(function(a){ return parseInt(a,10); });
    document.body.removeChild(a);
    return (colors.length >= 3) ? '#' + (((1 << 24) + (colors[0] << 16) + (colors[1] << 8) + colors[2]).toString(16).substr(1)) : false;
}
getHexColor('teal') // returns #008080

Explanation by line:

• Create html element
• Set the color
• Get the rgb-code form the element which is just appended to the body (so it is rendered), filter numbers and convert each number to an integer.
• Remove the html element we just created
• Return the HEX code using zyklus code (see credits for more info)

credits to zyklus for his rgb to hex code

Answer 6

Here's an all purpose solution that does exactly what you want in every browser that is 100% programmatic, goodbye giant static table of names and hex values!:

// Here is the solution tied together as a native String native extension using 
// MooTools, though you can implement the same thing in whatever framework you prefer:

(function(String){

var valueMatch = {
        'rgb(0,0,0)': { 'black': ' ', 'rgb(0,0,0)': ' ' },
        'rgba(0,0,0,0)': { 'transparent': ' ', 'rgba(0,0,0,0)': ' ' },
        '#ffffff': { 'transparent': ' ' },
        'transparent': { 'transparent': ' ' }
    },
    colorFromProbe = function(color){
        color = color.toString();
        if(!color.match(/^#.+$|^[^0-9]+$/)) return color;
        var probe = ($('moo_color_probe') || new Element('textarea', {
                'id': 'moo_color_probe',
                'styles': {
                    'display': 'none',
                    'color': 'transparent'
                }
            }).inject(document.body, 'after'));
        try{ probe.setStyle('color', color) } catch(e){ return color } //IE throws an error instead of defaulting the style to some color or transparent when the value is unrecognized
        var computed = (Browser.ie) ? ieColorToHex(probe) : (Browser.opera) ? probe.style.color : probe.getComputedStyle('color'),
            match = valueMatch[computed.replace(/ /g, '')];
        probe.setStyle('color', 'transparent');
        if((!Browser.ie || Browser.ie9) && color == 'transparent' && (match && match['transparent'])) return 'rgba(0, 0, 0, 0)';
        return (computed == 'transparent' || match && !match[color.replace(/ /g, '')]) ? color : computed;
    },
    ieColorToHex = function(probe){ // Special IE mojo, thanks to Dean Edwards for the inspiration, his code used a pop-up window to test the color, I found you can simply use a textarea instead ;)
        var value = probe.set('value', '').createTextRange().queryCommandValue("ForeColor");
        value = (((value & 0x0000ff) << 16) | (value & 0x00ff00) | ((value & 0xff0000) >>> 16)).toString(16);
        return "#000000".slice(0, 7 - value.length) + value;
    };

    String.implement({
        colorToRgb: function(){
            var color = colorFromProbe(this);
            return (color.charAt(0) == '#') ? color.hexToRgb() : color;
        },
        colorToHex: function(){
            var color = colorFromProbe(this);
            return (color.test('rgb')) ? color.rgbToHex() : color;
        }
    });

})(String);

Answer 7

You'll need to rely on getComputedStyle(...).

Example of using getComputedStyle:

function convertToHexColor(englishColor) {

    // create a temporary div. 
    var div = $('<div></div>').appendTo("body").css('background-color', englishColor);
    var computedStyle = window.getComputedStyle(div[0]);

    // get computed color.
    var computedColor = computedStyle.backgroundColor;

    // cleanup temporary div.
    div.remove();

    // done.
    return computedColor;

    // The above returns "rgb(R, G, B)" on IE9/Chrome20/Firefox13.
};

And to convert "rgb(R, G, B)" to #RRGGBB you can use:

function convertRGBDecimalToHex(rgb)
{
    var regex = /rgb *\( *([0-9]{1,3}) *, *([0-9]{1,3}) *, *([0-9]{1,3}) *\)/;
    var values = regex.exec(rgb);
    if(values.length != 4)
    {
        return rgb; // fall back to what was given.              
    }
    var r = Math.round(parseFloat(values[1]));
    var g = Math.round(parseFloat(values[2]));
    var b = Math.round(parseFloat(values[3]));
    return "#" 
        + (r + 0x10000).toString(16).substring(3).toUpperCase() 
        + (g + 0x10000).toString(16).substring(3).toUpperCase()
        + (b + 0x10000).toString(16).substring(3).toUpperCase();
}

Answer 8

Download & include the w3color.js from w3school.

then in your script you can use any of the following functions:

let c = w3color("violet");
c.darker(n)
c.desaturate(n)
c.isDark(n)
c.lighter(n)
c.saturate(n)
c.toCmyk()
c.toCmykString()
c.toCmykStringDecimal()
c.toHexString()
c.toHsl()
c.toHslString()
c.toHslStringDecimal()
c.toHslaString()
c.toHwb()
c.toHwbString()
c.toHwbStringDecimal()
c.toHwbaString()
c.toName()
c.toNcol()
c.toNcolString()
c.toNcolStringDecimal()
c.toNcolaString()
c.toRgb()
c.toRgbString()
c.toRgbaString()

Answer 9

Run the snippet to see how easily "any" valid CSS color (HSL, names, hex, system colors*, etc.) can be converted to R/G/B values using any element you happen to have laying around.

*Enter a value of background and you'll get your Windows Desktop background color (in Firefox, anyways).

go();
function go() {
  clr.style.backgroundColor = document.getElementById('txt').value;
  document.getElementById('rgb').innerHTML = window.getComputedStyle(clr).backgroundColor;
}

* { margin:0; box-sizing:border-box; font-family:verdana; overflow:hidden; }
#txt,#rgb,#clr { height:30vh; width:97vw; padding:5vmin; margin:2vmin; font-size:13vh; border:1vmin solid; text-align:center; vertical-align:middle;}
#txt{margin-bottom:0;}

<input type='text' id='txt' onkeyup='go()' value='chartreuse' placeholder='Enter any css color . . .' autofocus>
<div id='clr'></div>
<div id='rgb'></div>

some test cases:

console.log("rgba(100,100,0,0.7)".colorNameToHex());  //returns undefined 
console.log("rgba(100,100,0,0.7)".colorNameToHex(1)); //returns rgba(100,100,0,0.7) 

as a bonus here my use case for that in a color-string to color-string-with-alpha conversion:

works with any css defined color including: rgba, rgb, r%g%b%, #rgb, #rrggbb, hsl, hsla

mostly useful in drawing with alpha/opacity/transparency onto a HTML5 canvas element with passed on color strings

String.prototype.setAlpha = function (alpha) {
    // change alpha of color string in any css color space
    // intended for use in canvas/svg
    // currently implemented:
    // css defined colors               > rgba
    // rgba, rgb, r%g%b%, #rgb, #rrggbb > rgba
    // hsl, hsla                        > hsla
    // unresolved                       > as is
    //
    // If no alpha is passed its is set to 1 or keeps the value in rgba/hsla

    // kill whitespace split at "(", ")", ","
    var i, hex, c = this.replace(/\s/g, '').split(/[\(\),]/);
    function extractHex(string) {
        if (string.charAt(0) === "#") {  // detect hex strings
            hex = string.replace(/#/g, '');
            string = "hex";
        } else {hex = undefined; }
        return string;
    }
    extractHex(c[0]);
    if (["rgba", "rgb", "hsla", "hsl", "hex"].indexOf(c[0]) === -1) {
        c[0] = extractHex(c[0].colorNameToHex(1)); // detect defined color names
    }
