Ultimate Guide to CSS Color Formats
Modern web engineering relies on multiple **color models** depending on technical requirements:
* **HEX & RGB**: The native pixel-level models used by hardware displays. HEX uses base-16 strings while RGB defines channels between 0 and 255.
* **HSL & HSV**: Human-intuitive cylindrical coordinate models. HSL stands for Hue, Saturation, and Lightness, making adjustments to lighting much simpler.
* **CMYK**: The primary subtractive color model used in printing pipelines. Having accurate conversions is vital when translating digital interfaces to print guidelines.
Pro Tip:
Simulating Deuteranopia and Protanopia (red-green blindness) during layout design stages ensures complete accessibility compliance!
