HTML Color Codes

HTML color codes are essential for web designers and developers to specify colors in their web pages. These codes provide a standardized way to represent colors across different browsers and devices.

Hexadecimal Color Codes

The most common format for HTML color codes is hexadecimal. It consists of a hash symbol (#) followed by six characters representing red, green, and blue values.

<p style="color: #FF0000;">This text is red</p>
<div style="background-color: #00FF00;">This div has a green background</div>

RGB and RGBA Color Codes

RGB (Red, Green, Blue) and RGBA (Red, Green, Blue, Alpha) color codes offer an alternative method to specify colors in HTML. The alpha value in RGBA determines the opacity of the color.

<p style="color: rgb(255, 0, 0);">This text is red</p>
<div style="background-color: rgba(0, 255, 0, 0.5);">This div has a semi-transparent green background</div>

HSL and HSLA Color Codes

HSL (Hue, Saturation, Lightness) and HSLA (Hue, Saturation, Lightness, Alpha) provide yet another way to define colors in HTML. This format can be more intuitive for some designers.

<p style="color: hsl(0, 100%, 50%);">This text is red</p>
<div style="background-color: hsla(120, 100%, 50%, 0.5);">This div has a semi-transparent green background</div>

Color Names

HTML also supports a set of predefined color names. While not as flexible as numerical codes, they can be useful for quick prototyping or when exact color precision isn't crucial.

For a comprehensive list of color names, refer to the HTML Color Names guide.
