Why convert between color formats?
Web development uses multiple color notations for different purposes. HEX codes (#9F7AEA) are compact and widely used in design tools like Figma and Sketch. RGB values are needed for programmatic color manipulation in JavaScript and Canvas APIs. HSL (Hue, Saturation, Lightness) is the most intuitive format for creating color palettes because you can adjust brightness or saturation without changing the hue.
When to use each format
Use HEX in CSS when you want short, readable color declarations. Use RGB or RGBA when you need transparency (alpha channel) or are computing colors in JavaScript. Use HSL when building design systems — it makes it easy to generate consistent tints and shades by adjusting the lightness value while keeping hue and saturation constant. Modern CSS supports all three formats natively.
Color in modern CSS
CSS now supports color-mix(), relative color syntax, and the oklch() color space for perceptually uniform colors. Understanding how HEX, RGB, and HSL relate to each other is foundational knowledge for any frontend developer working with design tokens, dark mode themes, or accessible color contrast ratios that meet WCAG 2.1 AA standards.
