I think I found a literal Wonka golden ticket - enemy Twitch died to my friend's Mel W and dropped a GOLD Senna wraith I could pick up
I'm on Lunar Eclipse Senna with Pearl chroma.

Enemy Twitch popped R, auto'd my friend's Mel, he hit Rebuttal (W), and the reflected shot killed Twitch. My wraith dropped gold. Not pale blue, gold. I walked over and collected it like it was any other wraith.
Checked the replay to make sure I wasn't imagining it. Reloaded it, rewound past the moment multiple times. Same result every single time. Not a rendering hiccup, something in the game logic is actually producing this.
Best guess (could be totally wrong): wraiths are hostile units, but only targetable by Senna, that's what lets her attack and collect them with AA, Q, or R. They also launch into the air briefly on spawn before settling into a static state, and while in flight during that airborne window, they get deleted on contact with Yasuo's Windwall, the same way a real projectile would. Rebuttal also works off missile collision. If the wraith briefly counted as that kind of object while airborne, it's possible Rebuttal caught it during that window the same way it catches any other projectile, and applied its gold recolor in the process.
Felt like finding Wonka's Golden Ticket.
