bookWorking with Colors

Colors play a vital role in web design, and CSS offers several ways to define them. You can use named colors, hex codes, rgb(), and rgba() formats.

  • Named colors such as "blue" or "red" are easy to remember and quick to use for standard hues, but they offer a limited palette;
  • Hexadecimal codes like #e67e22 provide more precise control and are widely used for branding and design consistency;
  • The rgb() format lets you specify exact red, green, and blue values, ranging from 0 to 255, which is especially helpful when you need a specific shade;
  • The rgba() format is similar to rgb() but adds an alpha value, which controls the color's transparency from 0 (fully transparent) to 1 (fully opaque).

Use rgba() when you want to layer colors or create overlays with varying opacity. By choosing the right format for your needs, you can achieve both creative flexibility and visual clarity in your styles.
