How naming works on Colname

  1. 01Every color falls into one of 32,768 registry slots.
  2. 02If a slot has no name yet, you can give it one — with a short story — using a free account.
  3. 03The name gets a permanent CN-ID and a public page you can share. Names are final once registered.

Standard naming is free until December 31, 2026. A name is a public registry record — not a trademark, copyright or legal ownership of the color.
