Are Oranges Dyed to Be That Shade of Orange?

Updated: Apr. 05, 2024

In the store, pyramids of brightly-colored citrus catch shoppers' eyes. Is the skin that orange—or are oranges dyed?

The produce department in your grocery store is bursting with bright leafy greens, red tomatoes, yellow bananas and, of course, orange oranges. But are oranges really orange? Or are oranges dyed to look more appealing?

It depends on when—and where—the oranges were harvested.

Why Oranges Might Be Dyed

When oranges are harvested, the peels might not be quite orange enough to visually appeal to shoppers. The peels might even still be green! Shoppers prefer to purchase fruits and vegetables with fresh, bright colors, so some growers spray citrus with Citrus Red No. 2.

Here’s an explanation, straight from the FDA: “It is a common practice to color the skins of oranges in certain orange growing areas of the country because of climatic or cultural conditions which cause the oranges to mature while still green in color.”

In this case, “certain orange growing areas of the country” means the state of Florida.

Citrus Red No. 2 has been approved by the FDA since 1956, so this practice is nothing new. It shouldn’t affect the taste or texture of your citrus. Citrus Red No. 2 isn’t water-soluble, but do still wash your fruit. Before you eat, run oranges under cool water for a minute, then dry with a clean kitchen towel.

How to Know If Oranges Are Dyed

Not all oranges harvested in the US have a coat of Citrus Red No. 2.:

  • Citrus Red No. 2 is banned for citrus grown in California and Arizona
  • It’s only used to color the skin of non-organic oranges
  • No oranges intended for processing have Citrus Red No. 2, so this dye won’t be present in OJ

So there you have it: Most but not all oranges are naturally orange. To choose ripe oranges at the store, don’t focus only on the color—look for in-season fruit with heft and firm flesh.
