Color Formats for CSS
CSS accepts several color formats. Choosing well makes stylesheets easier to maintain.
Pick by intent
Use HEX for set colors, RGB or HSL with an alpha channel for transparency, and HSL when you derive related colors. The converter lets you move between them freely.
Theming with HSL
Design systems often define colors in HSL so a single hue can spawn a consistent scale of lightness. Converting existing colors to HSL is the first step toward that approach.
