When to Use Hex, RGB, and HSL in CSS

Hex codes like #6C63FF are the most compact color notation and work everywhere in CSS. They are ideal for design tokens and static color values. RGB notation gives you arithmetic flexibility: if you store colors as CSS custom properties, you can use them in rgba(var(--color-primary-rgb), 0.4) to create transparent variants without rewriting the hex. HSL is the format to reach for when you want to programmatically generate color scales. Adjusting only the L (lightness) value from 20% to 90% while keeping hue and saturation fixed gives you a consistent tint stack for a component library. For example, the color hsl(243, 100%, 69%) is the blue-purple #6C63FF. Changing L to 95% gives a very light background tint; changing L to 30% gives a dark pressed state, all from the same hue. This is why design systems like Tailwind generate their palettes in HSL. Knowing how to convert quickly between these formats saves time when matching a designer's Figma spec to your actual CSS code.
