Question: what is the difference between a red onion and a bermuda onion?
Answer: I've heard these called “Bermuda Onions” but apparently that's a misnomer as actual Bermuda onions are not purple or red: ... They are not red onions, or Spanish onions. They are flat-topped, sweet onions which can have white or yellow skin. Varieties include Yellow Bermuda, White Bermuda and Crystal Wax.
