Field notes
The page separates the invented “pertulma” from the existing word “ultramarina,” which it connects to the blue pigment made with imported lapis lazuli. It credits organizer Andrés Londoño and says the challenge began in a WhatsApp group. The page also names distinct search indexes in its explanation of how AI assistants might find participating sites; those descriptions are the page’s account, rather than independently verified details.
