Frequently asked questions
Why do designers use hex codes instead of RGB?+
Hex packs all three channels into one short token (#ff0066) that’s quick to copy between CSS, design tools and code. It represents exactly the same colour as the RGB values — it’s just a more compact notation.
Will the hex code always be six digits?+
Yes. Each channel becomes two hexadecimal digits, so the result is a full six-digit code (plus the leading #). Some colours can also be written in three-digit shorthand, but the six-digit form is unambiguous and works everywhere.
What range should R, G and B be in?+
Each channel is an integer from 0 to 255 — values outside that range are rejected with a clear error.
Is my data uploaded anywhere?+
No. The conversion runs entirely in your browser — nothing is sent to a server.
