RGB, HEX and HSL: what's the difference?
RGB, HEX and HSL all describe the exact same colors — they're just different ways of writing the same numbers. RGB defines a color by how much red, green and blue light combine to make it, each on a 0–255 scale. HEX is the same RGB values rewritten as a compact 6-digit base-16 code, which is why rgb(31, 58, 95) and #1f3a5f are identical colors. HSL instead describes a color by hue (its position on a color wheel), saturation (how vivid it is) and lightness — a format that's often more intuitive for picking related shades.
Where each format is typically used
| Format | Typical use | Why |
|---|---|---|
| HEX | CSS, HTML, design tools | Short, easy to paste and share as a single string |
| RGB | CSS with transparency (rgba) | Supports an alpha channel for opacity |
| HSL | Building color palettes | Easy to create lighter/darker or related hues by changing one number |
Using these values in CSS
Any of the three formats work directly in a stylesheet: color: #1f3a5f;, color: rgb(31, 58, 95); and color: hsl(210, 51%, 25%); all render the identical navy blue. HEX is the most common shorthand for solid colors, while RGB (or its rgba() variant) is useful when a color needs partial transparency, and HSL makes it straightforward to generate a consistent set of shades by keeping the hue fixed and only adjusting lightness.
