HTML Colors: A Guide to Adding Colors to Your Web Pages

HTML colors are an essential part of web development. They enhance the visual appeal of websites and improve the user experience. Colors can be applied to text, backgrounds, and borders using a variety of formats like HEX codes, RGB values, and HSL values. This guide will help you understand how to use colors in HTML with practical examples.

Types of HTML Color Formats

1. Color Names

HTML supports 140 predefined color names such as red, blue, green, and yellow. These names are simple and convenient to use for basic color applications.

<p style="color: red;">This text is red.</p>
    

2. HEX Color Codes

HEX codes are six-character strings beginning with a #. They allow you to specify exact colors.

<p style="color: #FF5733;">This text uses a HEX color.</p>
    

3. RGB Color Values

RGB stands for Red, Green, and Blue. You can create a wide range of colors by adjusting these three values.

<p style="color: rgb(0, 128, 255);">This text uses an RGB color.</p>
    

4. HSL Color Model

HSL stands for Hue, Saturation, and Lightness. This format is useful for creating harmonious color schemes.

<p style="color: hsl(240, 100%, 50%);">This text uses an HSL color.</p>
    

Applying Colors to HTML Elements

1. Text Color

Use the color property to change the text color.

<p style="color: green;">This text is green.</p>

Use the background-color property to set the background color of an element.

The border-color property lets you apply colors to borders.
