Colors on the web, including those used in WordPress, are most frequently represented in hexadecimal format. This system uses a six-character code to define colors, consisting of three pairs of two digits. Each pair represents the red, green, and blue components of a color, respectively, using values from 00 to FF in hexadecimal notation.

Using hexadecimal allows for a more compact representation of RGB colors, which is particularly beneficial for web design where simplicity and brevity in code are important. WordPress themes and customization often rely on this format for specifying colors in CSS and theme settings due to its widespread acceptance and ease of use.

While RGB, CMYK, and HSL are all valid color representations, they are not as commonly used in web development, particularly within the context of WordPress. RGB is more often represented in the format of "rgb(255, 0, 0)" for straightforward programming contexts but lacks the brevity of hex codes. CMYK is primarily used in print design rather than web design, and HSL, though useful in certain scenarios, is less prevalent than hexadecimal in standard web applications.
