Lucky you. I have’t seen a green one since 1981.
Copper burns green. Potassium burns purple.
What was the really showy meteor shower we had in the US maybe ten years ago? It was cold weather here in NC, so winter, I remember freezing my butt off to go outside and watch. Really amazing display, many different colors, some flaring up in one color and flaming out as another, with the larger ones leaving visible smoke trails. I’ve never seen anything like that before or since.
