Digital color theory: Conversion between HEX, RGB, HSL and Tailwind formats

The design of attractive and functional web interfaces depends largely on good color management. Computers and screens display colors by combining three light channels (Red, Green and Blue). However, there are different mathematical ways to define these mixtures in the source code.

The main color formats in web development

• HEX (Hexadecimal): The traditional format in HTML/CSS. Represents color channels in three hexadecimal pairs (#RRGGBB). It's compact but difficult to edit mentally.
• RGB (Red, Green, Blue): Defines the color using integer values ​​from 0 to 255 for each channel (e.g. `rgb(255, 0, 0)`).
• HSL (Hue, Saturation, Lightness): The preferred format for modern designers. By separating hue from intensity and brightness, it makes it easy to create harmonious palettes and design systems with dynamic dark modes.
• Tailwind CSS Arbitrary values: Colors tied to the Tailwind layout framework.
