Strange colour for Brimstone Bomb after death

I've never seen this before, that's why I'm reporting. I remember that bombs type mobs usually fell to the ground when defeated and kept the same colour until they became transparent and disappeared. Maybe it's just a matter of night time though. Anyways, it sounded odd for me.
Feel free to close this thread if this is working as intended.
