>>90045296Her main squid dress is sea green.
Her dress with the rainbow pattern is dark green, with green tights too.
Her season 2 dress with the spider necklace is a lighter dark green.
For one-off outfits, she wore green tights to Brittney's party, her bathing suit is sea green like her main dress, when she dressed up as Ludo that was obviously dark green too, her cactus headband that one time, and there might be more I'm forgetting.
She wears a ton of colors so I'm not trying to claim it's a signature color or anything, but she wears some shade of green a lot.
