Jellies come in all colors.

Jellyfishes are translucid, however some of them can have colored parts with red, pink, blue, violet or yellow pigments or with symbiotic microorganisms inside them, which give green or brown colorations. Microorganisms like zoochlorellae are greenish. zooxanthellae are brownish. Some jellyfishes, like Pelagia noctiluca or some Trachymedusae, are bioluminescent and can emit greenish or multicolored flashes.
