The concept of fallen angels having red feathers because their wings are bloodsoaked and never stopped bleeding after they plummeted to Earth.

That's why fallen angels can't go back to heaven. Their wings are too heavy with blood to fly back home.

Or black because the first time they fell from the scorch only they grew back white and they thought it looked cooler black so they dye it after.
