Color Format Guide
When to Use Each Format

Formate

HEX (#FF5733): Web. RGB (255,87,51): Bildschirm. HSL (9°,100%,60%): intuitiv. CMYK (0,66,80,0): Druck. Bildschirmfarben (RGB) und Druckfarben (CMYK) sind unterschiedlich — ein lebhaftes Rot am Bildschirm kann im Druck stumpf wirken.

Wann Welches

Web/CSS: HEX oder RGB. Design: HSL (Farbtoen leichter anpassen). Druckerei: CMYK obligatorisch.
