How to convert a hex color to RGB

1. Enter the hex code

   Drop the hex value into the "Hex (#RGB or #RRGGBB)" field. The leading `#` is optional and case doesn't matter — `#FF00aa` and `ff00aa` work equally.

2. Shorthand 3-digit expansion

   Three-digit hex is auto-expanded by doubling each digit: `#abc` becomes `#aabbcc` before parsing. Any length other than 3 or 6 valid hex digits is rejected with a clear error.

3. Press Run

   Result returns `r`, `g`, `b` (each 0–255), `rgbCss` (the ready-to-paste `rgb(r, g, b)` string), and `hex` (the normalised lowercase 6-digit form).

4. Use the rgbCss field directly

   rgbCss is formatted exactly how browsers expect it in inline styles. Copy it into your stylesheet, design tool, or component prop with no extra editing.
