Understanding Digital Color Models (HEX, RGB & HSL)
Whether you are designing a website, building an iOS/Android application, or preparing marketing assets, utilizing the correct digital color representation is crucial for design fidelity.
Color Models Explained
- HEX (#RRGGBB): A 6-character hexadecimal code representing Red, Green, and Blue intensity from 00 (0) to FF (255). Standard for HTML and CSS.
- RGB (rgb(r, g, b)): Represents additive colors via red, green, and blue light components ranging from 0 to 255.
- HSL (hsl(h, s, l)): Represents Hue (angle on the 360° color wheel), Saturation (percentage), and Lightness (percentage). Favored by UI designers because tinting and shading are intuitive.
