What color would methyl orange turn with grapefruit juice?

Well, isn't that a happy little question! Methyl orange is a dye that usually turns red in acidic solutions and yellow in alkaline solutions. Since grapefruit juice is acidic, it would likely turn methyl orange red, creating a vibrant and colorful reaction that shows the acidity of the juice. Just like painting a beautiful sunset, nature always provides us with lovely surprises!
