The "real" colour of a pomegranate is not a single hue, but rather a vibrant spectrum that varies significantly depending on the specific part of the fruit or plant, as well as its variety, ripeness, and growing conditions. This remarkable diversity contributes to its unique appeal.
A Spectrum of Pomegranate Hues
Pomegranates, from their outer skin to their edible arils and even their blossoms, display a wide array of colours. This extensive palette is a result of natural pigments and genetic variations across different types of pomegranates cultivated worldwide.
Pomegranate Fruit Skin Colours
The exterior of a pomegranate fruit presents a captivating range of colours that often indicate ripeness and variety. While many associate pomegranates with a deep red exterior, their skins can be far more diverse.
- White-yellow: Often seen in less common or earlier ripening varieties.
- Green: Typically indicates an unripe fruit, though some varieties retain a greenish hue even when ripe.
- Pink: A common colour, especially in varieties that are not fully mature or in certain sweeter types.
- Red: The most recognized and widespread colour for ripe pomegranate fruit skin, often signifying a classic, juicy fruit.
- Dark Purple: Found in specific, often more intensely flavoured varieties, adding a dramatic visual element.
The skin colour can be a helpful guide for consumers, though it's important to note that the internal quality isn't always directly proportional to the skin's redness for all varieties.

Pomegranate Aril Colours (The Edible Seeds)
Inside the fruit, the juicy arils—the edible, jewel-like sacs surrounding the seeds—also exhibit a broad spectrum of colours. These colours are primarily due to anthocyanins, powerful antioxidants.
- White: Found in specific, often very sweet varieties, indicating a lower concentration of anthocyanins.
- Light Pink to Dark Red: The most common range, with deeper reds often signifying higher antioxidant levels and a more intense flavour.
The colour of the arils is often a key indicator of the fruit's ripeness and flavour profile, with deeper red arils typically being sweeter and tangier.
Pomegranate Flower Colours
Before the fruit even develops, pomegranate trees produce beautiful flowers, which themselves showcase a range of colours.
- White-yellow: Less common but present in some varieties.
- Orange-red: A vibrant and striking colour, often seen in ornamental pomegranate trees.
- Deep Red: The most typical colour for pomegranate blossoms, which later develop into the fruit.
Why Such Variety?
The extensive colour range observed in pomegranates is influenced by several factors, including:
- Genetic Diversity: Different cultivars naturally produce varying pigment combinations.
- Ripeness: As the fruit matures, the concentration of pigments like anthocyanins increases, leading to deeper reds.
- Environmental Factors: Sunlight exposure, soil type, and climate can all impact the intensity and shade of the fruit's colour.
Summary of Pomegranate Colours
| Pomegranate Part | Color Range |
|---|---|
| Fruit Skin | White-yellow, Green, Pink, Red, Dark Purple |
| Arils | White to Deep Red |
| Flowers | White-yellow, Orange-red, Deep Red |
Understanding this diverse palette enhances appreciation for the pomegranate, highlighting that its "real" colour is a celebration of its natural variety.
