Colors are crucial in web design as they influence a user’s emotions and perceptions toward a brand or content. Appropriate color choices can boost engagement, convey information, and enhance aesthetics.

B. Overview of Color Representation

II. What is RGB?

A. Definition of RGB

RGB stands for Red, Green, and Blue, which are the three primary colors of light. By combining these colors in various intensities, you can produce a wide spectrum of colors for display on screens.

B. How RGB Works

In the RGB color model, each color channel is assigned a value ranging from 0 to 255. When combined, these values create a specific color. For instance, an RGB value of (255, 0, 0) represents pure red, while (0, 255, 0) stands for green.

B. Using RGB with HTML

To implement colors using RGB values in HTML, you can use them in your inline CSS, internal CSS, or external CSS.

V. How to Use RGB in HTML

A. Inline CSS

Inline CSS allows you to add styles directly to an HTML element. Here’s a simple example:

<p style="color: rgb(255, 0, 0);">This text is red!</p>

B. Internal CSS

Internal CSS involves including styles within a <style> tag in the head section of your HTML document. Below is an example:

<style>
  .blue-text {
    color: rgb(0, 0, 255);
  }
</style>
<p class="blue-text">This text is blue!</p>

C. External CSS

External CSS is utilized by linking to a separate CSS file. This method promotes better organization. Here’s how to link an external CSS file:

<link rel="stylesheet" type="text/css" href="styles.css">

In the styles.css file, you would define:

.green-text {
  color: rgb(0, 255, 0);
}
</code>

<p class="green-text">This text is green!</p>
