When it comes to the range of olive oils available, many factors influence customer choice but should the colour of olive oil influence your choice? Some bottles glow a deep, vibrant green. Others pour a warm golden yellow. Colour is a window into the olive’s journey from tree to bottle.
Here is a clear summary of what the colour of olive oil does and does not reveal about its quality, and how Morocco Gold’s distinctive colour reflects its flavour and health benefits.
What Determines Olive Oil Colour?
Olive oil colour is shaped by three main factors:
1. Olive Variety
Different olive cultivars naturally produce oils with different pigments.
- Some varieties are rich in chlorophyll, giving a green hue.
- Others contain more carotenoids, which create yellow or golden tones.
Neither pigment is inherently “better” — they simply reflect the olive’s natural chemistry.

2. Ripeness at Harvest
This is one of the biggest colour influencers.
- Early‑harvest olives (still green) contain more chlorophyll → greener oil
- Later‑harvest olives (purple or black) contain more carotenoids → more golden oil
Early-harvest oils tend to be more robust and peppery, while later-harvest oils are softer and fruitier.
3. Production Methods
Cold extraction preserves natural pigments. Heat, refining, or blending can strip colour — which is why refined oils often look pale or uniform.
Does Colour Reflect Quality?
Here’s the truth: colour alone does not determine quality.
High-quality extra virgin olive oil can be green, yellow, or anywhere in between. Quality is defined by:
- Acidity levels
- Freshness
- Polyphenol content
- Purity and production standards
A deep green oil might indicate early harvest and high polyphenols — but colour can also be manipulated. Some producers even add chlorophyll to make oil appear greener. This is why reputable producers rely on lab testing, not colour, to demonstrate quality.
Does Colour Indicate Health Benefits?
Colour can hint at certain compounds, but it’s not a reliable measure of health value.
- Chlorophyll contributes to the green colour and has antioxidant properties.
- Carotenoids (yellow pigments) also have antioxidant benefits.
However, the real health powerhouse in olive oil is polyphenols — and these are not visible to the eye. A pale oil can be high in polyphenols, and a green oil can be low, depending on harvest timing and processing.
Does Colour Affect Taste?
Absolutely — but indirectly.
Because colour reflects ripeness and pigment levels, it often correlates with flavour style:
- Greener oils
- More peppery
- More bitter (in a good way)
- More herbaceous
- Often higher in polyphenols
- Golden oils
- Softer, sweeter
- More buttery
- More delicate
- Often from riper olives
Taste is ultimately shaped by variety, terroir, and production — colour is just one clue.
Morocco Gold: What Its Colour Reveals
Morocco Gold Extra Virgin Olive Oil typically presents a clear, bright golden-green hue — a colour that reflects its unique combination of:
Early Harvest + Single Variety
Morocco Gold uses early-harvest Picholine Marocaine olives, which retain chlorophyll while also developing carotenoid warmth. This creates a balanced colour: neither intensely green nor pale yellow.
High Polyphenol Levels
This year’s harvest contains 228 mg/kg polyphenols, a level associated with:
- A fresh, vibrant flavour
- A gentle peppery finish
- Strong antioxidant benefits
Polyphenols don’t directly colour the oil, but early harvesting (which boosts polyphenols) often results in greener tones — exactly what you see in Morocco Gold.
Cold Extraction
The oil is extracted within hours of picking, preserving natural pigments and ensuring clarity rather than cloudiness.
What This Colour Means for You
Morocco Gold’s golden-green colour signals:
- Freshness
- Early harvest quality
- Balanced flavour profile
- High nutritional value
It’s a colour that reflects authenticity — not manipulation.
Final Thoughts: Colour Is a Clue, Not a Verdict
Olive oil colour is fascinating, but it’s not a reliable measure of quality on its own. Instead, think of colour as part of the story:
- Green oils often come from early harvests and may be more robust.
- Yellow oils often come from riper olives and may be smoother.
- Both can be exceptional when produced with care.
Morocco Gold’s distinctive golden-green hue is the natural result of its single-estate olives, early harvesting, and meticulous cold extraction — a colour that reflects the purity, flavour, and health benefits inside every bottle.
Our latest new harvest has an acidity level of 0.19% – which is the lowest we have ever achieved and our polyphenol level is 606mg/kg – again – well above the health benefits level of 250mg/kg.
