Red vs. White Onions: Key Differences
Color, size, and shape
As the name suggests, red onions are defined by their deep reddish-purple hue that fades into white at the base.

Red onions also contain certain compounds that provide an additional layer of complexity which gives them a subtle sweetness and slight bitterness. This makes them ideal for raw applications like salads or sandwiches.
