How to Convert Color Names to Hex Codes in Javascript

Color conversion can be a tedious task, especially if you need to manually code every possible combination. Fortunately, there are ways to simplify this process and save yourself some time.

Built-in Function

Despite its extensive functionality, Javascript does not natively provide a built-in function that can directly convert color names to their hexadecimal representations.

Custom Implementation

To address this limitation, you can create your own custom function using an external list of color names and their corresponding hex codes. Here's a code snippet that demonstrates how to do this:

function colourNameToHex(colour) {
    var colours = {
        "aliceblue": "#f0f8ff",
        "antiquewhite": "#faebd7",
        // Additional color names and hex codes go here
    };

    if (typeof colours[colour.toLowerCase()] != 'undefined') {
        return colours[colour.toLowerCase()];
    }

    return false;
}

Usage

To use the colourNameToHex function, simply pass the color name as an argument and it will return its hexadecimal code. For example:

console.log(colourNameToHex('red')); // Outputs: #ff0000
console.log(colourNameToHex('chartreuse')); // Outputs: #7fff00

Custom List

The example provided includes a few color names for demonstration purposes. You can extend this list to cover all the color names you need by referring to a comprehensive list of colors and their hex codes, such as the one found here: https://www.w3schools.com/colors/colors_names.asp
