Many designers prefer HSL for its intuitive relationship to color properties
Frequently Asked Questions
What is the difference between HEX and RGB?
HEX is a 6-digit hexadecimal code (e.g., #FF5733). RGB expresses the same color as red, green, blue values (e.g., rgb(255, 87, 51)). Both represent the same color.
What is HSL?
HSL (Hue, Saturation, Lightness) is more intuitive for design: hue is the color angle (0-360°), saturation is the intensity (0-100%), lightness is brightness (0-100%).
