Arduino days 2025 Cotonou at Seme City Open Park Hackathon's project : The crypt at forgotten colors

An ancient chest has been sealed for generations in the darkness of a forgotten crypt. A riddle engraved on the walls draws your attention: “Red and Blue unite to reveal the invisible.” In front of you, a three-colored lantern flickers faintly. Only a precise blend of colors will reveal the secret ritual and open the chest. Can you restore the forgotten color and unlock the secrets of the crypt?
