How to Create a Color Palette Generator From Hex Code

1. The following HTML structure defines the layout of your color palette generator. Copy and paste it on your web/app project where you want to display color palettes. Customize it to fit your website’s design.

<div class="container">
        <div class="color-palette">
            <div class="color">
                <div class="color-alt"></div>
            </div>
            <div class="color">
                <div class="color-alt"></div>
            </div>
            <div class="color">
                <div class="color-alt"></div>
            </div>
            <div class="color">
                <div class="color-alt"></div>
            </div>
        </div>
</div>
<div class="button-container">
    <div><button class="buttons" onclick="start()">random compatible </button></div>
 
    <div>
        <button class="buttons" onclick="start('red')">red off</button>
        <button class="buttons" style="background: linear-gradient(to right, rgb(252, 9, 9), rgb(255, 187, 0), rgb(236, 29, 226));" onclick="start('redlight')"></button>
        <button class="buttons" style="background: linear-gradient(to right, rgb(252, 9, 9), rgb(8, 8, 8));" onclick="start('reddark')"></button>
    </div>

    <div>
        <button class="buttons" onclick="start('green')">green off</button>
        <button class="buttons" style="background: linear-gradient(to right, rgb(66, 252, 9), rgb(247, 216, 131),rgb(4, 255, 234));" onclick="start('greenlight')"></button>
        <button class="buttons" style="background: linear-gradient(to right, rgb(29, 243, 10), rgb(23, 114, 4),rgb(3, 32, 1));" onclick="start('greendark')"></button>
    </div>

    <div>
        <button class="buttons" onclick="start('blue')">blue off</button>
        <button class="buttons" style="background: linear-gradient(to right, #00b9ff, #f295fa,rgb(136, 11, 130));" onclick="start('bluelight')"></button>
        <button class="buttons" style="background: linear-gradient(to right, rgb(25, 9, 252), rgb(31, 17, 82),rgb(1, 2, 14));" onclick="start('bluedark')"></button>
    </div>
</div>

2. Use the following CSS code to style the color palette and buttons. Adjust the styles to match your website’s theme.

*{
    box-sizing: border-box;
    padding: 0;
    margin: 0;
}

body{
    font-family: consolas;
}

.color-palette{
    display: flex;
    flex-direction: column;
    width: 300px;
    height: 270px;
    box-shadow: 0 0 30px #0000002f;
    border-radius: 11px;
    overflow: hidden;
}

.container{
    padding: 20px;
    display: flex;
    align-items: center;
    justify-content: center;
}

.color{
    display: flex;
    align-items: flex-end;
    justify-content: end;
    height: 25%;
    cursor: pointer;
}
.color:hover .color-alt{
    transform: scale(1);
}
.color-alt{
    transform: scale(0);
    display: flex;
    align-items: center;
    justify-content: center;
    background: #00000050;
    color: #fff;
    height: 35px;
    width: 100px;
    border-radius: 15px 0 0 0;
    overflow: hidden;
}
.copys{

    position: relative;
}
.copys::before{
    display: flex;
    align-items: center;
    justify-content: center;
    content: "Copied";
    position: absolute;
    left: 0;
    top: 0;
    width: 100%;
    height: 100%;
    background: rgb(0, 0, 0);
}
.button-container{
    display: flex;
    align-items: center;
    flex-direction: column;
}

.button-container > div{
    display: flex;
    gap: 15px;
    margin: 15px 0;
}

.buttons{
    border: none;
    outline: 0;
    width: 200px;
    height: 50px;
    cursor: pointer;
    border-radius: 6px;
}
.buttons:hover{
    transform: scale(1.02);
}

3. Now, let’s add the JavaScript functionality to make the color palette generator work. Copy and paste the following JavaScript code into your JS file.

var color = document.querySelectorAll(".color")
var coloralt = document.querySelectorAll(".color-alt")
var container = document.querySelector(".container")

function start(event) {
    function randomColorGen() {
        
        hexColor = "#" + (Math.random() * 0xFFFFFF << 0).toString(16);
        hexColorRe = hexColor.substring(0, 1) + hexColor.substring(1, 7).split("").reverse().join("");

        //red ssettings
        if (event === 'red') {
            hexColor = hexColor.substring(0, 1) + "00" + hexColor.substring(3, 5) + hexColor.substring(5);
            hexColorRe = hexColorRe.substring(0, 1) + "00" + hexColorRe.substring(3, 5) + hexColorRe.substring(5);
        }
        if (event === 'redlight') {
            hexColor = hexColor.substring(0, 1) + "ff" + hexColor.substring(3, 5) + hexColor.substring(5);
            hexColorRe = hexColorRe.substring(0, 1) + "ff" + hexColorRe.substring(3, 5) + hexColorRe.substring(5);
        }
        if (event === 'reddark') {
            hexColor = hexColor.substring(0, 1) + hexColor.substring(1, 3) + "00" + "00";
            hexColorRe = hexColorRe.substring(0, 1) + hexColorRe.substring(1, 3) + "00" + "00";
        }
        //----------------------------

        //green settings
        if (event === 'green') {
            hexColor = hexColor.substring(0, 1) + hexColor.substring(1, 3) + "00" + hexColor.substring(5);
            hexColorRe = hexColorRe.substring(0, 1) + hexColorRe.substring(1, 3) + "00" + hexColorRe.substring(5);
        }
        if (event === 'greenlight') {
            hexColor = hexColor.substring(0, 1) + hexColor.substring(1, 3) + "ff" + hexColor.substring(5);
            hexColorRe = hexColorRe.substring(0, 1) + hexColorRe.substring(1, 3) + "ff" + hexColorRe.substring(5);
        }
        if (event === 'greendark') {
            hexColor = hexColor.substring(0, 1) + "00" + hexColor.substring(3, 5) + "00";
            hexColorRe = hexColorRe.substring(0, 1) + "00" + hexColorRe.substring(3, 5) + "00";
        }
        //----------------------------

        //blue settings
        if (event === 'blue') {
            hexColor = hexColor.substring(0, 1) + hexColor.substring(1, 3) + hexColor.substring(3, 5) + "00";
            hexColorRe = hexColorRe.substring(0, 1) + hexColorRe.substring(1, 3) + hexColorRe.substring(3, 5) + "00";
        }
        if (event === 'bluelight') {
            hexColor = hexColor.substring(0, 1) + hexColor.substring(1, 3) + hexColor.substring(3, 5) + "ff";
            hexColorRe = hexColorRe.substring(0, 1) + hexColorRe.substring(1, 3) + hexColorRe.substring(3, 5) + "ff";
        }
        if (event === 'bluedark') {
            hexColor = hexColor.substring(0, 1) + "00" + "00" + hexColor.substring(5);
            hexColorRe = hexColorRe.substring(0, 1) + "00" + "00" + hexColorRe.substring(5);
        }
        //----------------------------


        container.style.background = `linear-gradient(to bottom, ${hexColor.substring(0, 7) + "50"},${hexColorRe.substring(0, 7) + "50"})`;
    }

       

    for (let i = 0; i < color.length; i++) {
        randomColorGen()
        color[0].style.backgroundColor = hexColor;
        color[1].style.backgroundColor = hexColorRe;
        coloralt[0].innerHTML = hexColor;
        coloralt[1].innerHTML = hexColorRe;

    }
    for (let i = 0; i < color.length; i++) {
        randomColorGen()
        color[2].style.backgroundColor = hexColor;
        color[3].style.backgroundColor = hexColorRe;
        coloralt[2].innerHTML = hexColor;
        coloralt[3].innerHTML = hexColorRe;

    }
}

for (let i = 0; i < color.length; i++) {
    color[i].addEventListener("click", ()=>{
        navigator.clipboard.writeText(coloralt[i].textContent)
        coloralt[i].classList.add("copys")
        setTimeout(() => {
            coloralt[i].classList.remove("copys")
        }, 500);
    })   
}
