Chromas & Z-Trails are unlockable cosmetic changes to Ekko and his Z-Trail particles.
You earn most of them through the hidden Chests found throughout the game, Kaleidosalts are for unlocking Chromas & Kaleidolilies are for unlocking Z-Trails. There are 2 Chromas & 2 Z-Trails exclusive to owning the DLC or Deluxe Edition of the game, and 1 final Chroma was only obtainable as a pre-order bonus.
Equipping them takes place at Elie’s Shop in the Hub at Entresol. Elie’s Shop becomes available during Chapter II of the main story.
