Building a Random Color Panel using JavaScript, HTML, and CSS

In this article, we will explore how to build a random color panel using only JavaScript, HTML, and CSS. The panel will consist of multiple boxes, each displaying a randomly generated hexadecimal color. By clicking a button, users will be able to refresh the colors and generate new combinations.

1. Introduction

The random color panel is a simple yet visually appealing project that can be useful for various purposes, such as finding inspiration for color schemes in coding projects. The panel will display a grid of boxes, each representing a distinct color. By clicking a button, users can instantly refresh the colors and explore new combinations.

2. Building the Random Color Panel

To begin building the random color panel, we will first set up the basic structure of the HTML file. This will include the necessary HTML tags and elements to create the panel and button.

2.1 Creating the Button

Inside the body tags, we will create a button element with an id of "button". This button will serve as the trigger for refreshing and generating new colors. We will add an onclick event to the button, which will reload the page upon clicking.

<button id="button" onclick="location.reload()">Refresh</button>

2.2 Generating Random Colors

Next, we will add a script tag to the HTML file to write the JavaScript code responsible for generating the random colors.

// Code for generating random colors

We will create a JavaScript function called "randomColor()" that will handle the generation of a random hexadecimal color. This function will utilize a set of characters, ranging from 0 to 9 and A to F, to create all possible combinations of hexadecimal colors.

function randomColor() {
    var chars = "0123456789ABCDEF";
    var color = "";

    // Generate a random color by selecting six random characters from the set
    for (var i = 0; i < 6; i++) {
        color += chars[Math.floor(Math.random() * chars.length)];

    return "#" + color; // Return the random color

3. Creating the CSS Styling

Now that we have set up the basic structure and JavaScript code for generating random colors, we can proceed to add CSS styling to enhance the visual appearance of the random color panel.

3.1 Styling the Boxes

To style the boxes, we will use the class name "box" and apply CSS properties to customize their appearance. We will set the width and height of each box to 200 pixels, assign a red background color for better visibility during development, and add some margin for spacing. Additionally, we will utilize flexbox properties to center the content both horizontally and vertically within each box.

.box {
    width: 200px;
    height: 200px;
    background-color: red;
    margin: 10px;
    display: flex;
    justify-content: center;
    align-items: center;

3.2 Creating the Grid Layout

To arrange the boxes in a grid layout, we will apply CSS properties to the body tag. This will allow us to control the number of columns in the grid, as well as the gap between the columns.

body {
    display: grid;
    grid-template-columns: repeat(6, auto);
    column-gap: 10px;

4. Applying Colors to the Boxes

In order to display the randomly generated colors within the boxes, we need to modify our JavaScript code to apply the colors to the respective elements. We will use the DOM querySelectorAll method to select all the boxes with the class name "box", and then iterate through each box to assign a random color.

function addColor() {
    var randomBoxes = document.querySelectorAll(".box");

    randomBoxes.forEach(function(box) {
        var randomColor = randomColor(); = randomColor;
        box.innerHTML = randomColor;

5. Troubleshooting and Testing

During the development process, it is important to test the functionality and visual appearance of the random color panel. It is recommended to use the browser's developer tools to identify any errors or issues. Additionally, ensure that the button is properly linked to the function and that the CSS styles are being applied correctly.

6. Making it Responsive

To make the random color panel responsive, we can utilize CSS media queries to adapt the layout based on different screen sizes. This will ensure that the panel looks great on various devices, including mobile phones and tablets. By adjusting the width and height of the boxes, as well as the number of columns in the grid, we can create a more user-friendly experience.

7. Enhancing the Functionality

To further enhance the functionality of the random color panel, there are several additional features that can be implemented. For example, we can add a copy button that allows users to easily copy the hexadecimal color code to their clipboard. We can also include a slider or input field that allows users to control the number of boxes generated.

8. Conclusion

In conclusion, building a random color panel using JavaScript, HTML, and CSS can be a fun and engaging project. By following the steps outlined in this article, you can create a visually appealing panel that generates random hexadecimal colors at the click of a button. Remember to experiment with different CSS styles and functionalities to truly make the project your own. Enjoy exploring the vast possibilities of color combinations!
