The Random Colour Generator project is a very helpful project for beginners who want to become web developers or Javascript developers in the future.

The Random Colour Generator javascript project can generate new and random colours each time the user clicks on the Generate Colour button.

Here's how it can benefit you:

1. Helps in learning basic Javascript concepts like how to create and use functions in Javascript.
2. DOM Manipulation Document Object Model (DOM) by selecting elements, changing styles, and responding to user actions like clicks.
3. Event Handling: how to attach event listeners to HTML elements for creating interactive web pages.
4. It's helpful in understanding colour theory and enhancing user interface (UI) skills.

How to Design a Random Color Generator:

Create the basic layout or structure of the Random Color Generator using various HTML code, like adding a button that will trigger the generation of a random color and adding a container or text element that will display the generated colour.

Use CSS to style the button and the container where the color will be displayed. Add some styling to the body and other elements to centre them on the page.

Once the layout is created, we need to create JavaScript file, create a function that generates a random color in hexadecimal format. Add an event listener to the button so that when it's clicked, the random color is generated and applied to the background of the container. Update the text in the container to show the hexadecimal value of the color.
