Understanding Color Codes

Before we dive into the specifics of Royal Blue's color code, it's essential to understand the concept of color codes. A color code is a numerical representation of a color, used to ensure consistency in printing and digital design. The most common color code system is RGB, which represents colors using red, green, and blue light. Another widely used system is HSL, which represents colors using hue, saturation, and lightness.

Hexadecimal color codes, represented by a hash (#) followed by six hexadecimal digits, are also commonly used. These codes are based on the RGB system but provide a more convenient and compact way to represent colors in web design. Now, let's explore the Royal Blue color code in different systems.
