What is on rainbow roll?

I'm curious, could you please elaborate on what exactly is included in a rainbow roll? I've heard it's a colorful and delectable sushi creation, but I'm unsure of the specific ingredients that make up this dish. Are there any special toppings or sauces that are commonly used to create the rainbow effect? And, does it differ from traditional sushi rolls in terms of flavor or texture? I'd love to hear more about this visually appealing and potentially tasty dish.
