Before a dish is tasted, it has already been judged. Before the first bite, the brain has formed an opinion — whether this looks appetising, whether it seems sweet or savoury, whether it inspires trust or hesitation. And almost always, that judgement comes from one thing alone: how it looks.
The colour of food is not decoration. It is information. The brain processes it before the fork has moved, and it shapes what we are about to taste. A young field of science called gastrophysics has been studying this for decades — and what it has found changes how thoughtful cooks approach the table.
We Eat With Our Eyes — The Science Behind It
The phrase “we eat with our eyes” has been repeated so often that it has lost its force. But behind the cliché lies a measurable, reproducible phenomenon. The human brain constructs expectations about flavour based on visual cues — and those expectations become part of the flavour itself. They influence how we perceive everything that follows.
Experimental psychology has been demonstrating this for decades. Sight does not accompany taste: it leads it. The visual experience of a dish is not the preamble to eating — it is the first course.
What Gastrophysics Says About Colour
Gastrophysics is a relatively recent discipline that studies how all the senses interact during eating. Its most prominent figure is Charles Spence, Professor of Experimental Psychology at the University of Oxford and author of Gastrophysics: The New Science of Eating. His research has consistently shown that the colour of food is one of the most powerful factors shaping how we perceive it.
The Red-Tinted White Wine Experiment
One of the most cited studies in this field was originally conducted at the University of Bordeaux and later replicated at Oxford. Oenology students were given a white wine to taste — to which an odourless red dye had been added. The tasters described it using the vocabulary of a red wine entirely: notes of red fruit, tannins, body. Not one of them detected the white wine that was actually in the glass. Colour had rewritten the flavour.
The Strawberry Mousse on White vs. Black Plate
Another study, developed by the Alicia Foundation alongside the elBulli team, served the same strawberry mousse on two different plates: one white, one black. Diners rated the mousse served on the white plate as 10% sweeter and 15% more flavourful than the identical mousse on the black plate. Same recipe, same kitchen — different chromatic context.
Why the Brain Conflates What It Sees With What It Tastes
The explanation lies in how sensory processing works. The brain does not integrate the senses in sequence — it combines them into a single, unified experience. When colours and flavours are congruent (red and sweet, green and acidic, golden and rich), the brain confirms what it anticipated. When there is dissonance, the experience becomes confused or disappointing, even if the dish is technically exceptional. Expectation is not separate from flavour — it is flavour.
What Each Colour Evokes at the Table
These associations are not universal — they are shaped by culture, memory and context. But within the contemporary Western table, certain patterns are remarkably stable.
Red
Associated with ripeness, sweetness, intensity. Red stimulates appetite. It evokes ripe fruit — strawberry, tomato, raspberry — and comforting, familiar flavours. A red dish is perceived as more flavourful before the first bite is taken.
Green
Associated with freshness, vegetation, acidity, and a hint of bitterness. Green activates the idea of health, of the raw and the unprocessed. In olive oils, a deep, vivid green announces character — bitterness and peppery finish — and it usually delivers.
Yellow and Gold
Associated with softness, gentle sweetness, familiarity. Gold inspires confidence. Many traditional olive oils lean into this palette for exactly that reason: a golden hue reads as warm, approachable, safe.
Black and Deep Purple
Associated with sophistication, depth, and intensity. But in excess, these colours suppress appetite. A predominantly black plate tends to reduce the perceived flavour of many foods — which is why they are used with precision, not abandon, in serious kitchens.
Pink
Unexpected. Ambiguous. Disruptive. When pink appears in a context where it is not anticipated — in a condiment, in an oil, in something fundamentally savoury — the brain enters a state of heightened attention. It pays closer attention to what it is about to taste. This is the effect that contemporary chefs exploit when working with edible flowers, beetroot, hibiscus, and natural pigments: not novelty for its own sake, but a deliberate invitation to taste more carefully.
How to Use Colour in Your Kitchen
None of this requires converting a kitchen into a photography studio. The shifts are small, and their effect is real.
Consider the plate. White is the most versatile surface: it enhances the natural colours of food and tends to amplify sweetness and flavour perception. Black works beautifully for dishes that are already dark, intense, and confident. If you are choosing one set of plates for everything, white is rarely wrong.
Work with contrast. A monochrome plate — everything the same tone — bores the brain before the first mouthful. A single chromatic note that stands apart from the rest — a vivid green against pale beige, a red against white — activates attention and anticipation.
Don’t disguise natural colour. If an ingredient is naturally vivid — the orange of a carrot, the green of a herb oil, the yellow of a good yolk — let it show. Covering it with a sauce that masks the colour removes a layer of flavour before the dish reaches the table.
And do not underestimate the oil. Olive oil appears on almost every dish, yet its colour is rarely considered as a deliberate ingredient. A deep green oil announces character. A pink oil changes the conversation entirely.
Olive Oil Is a Colour Too
Olive oil has always been a chromatic protagonist — it just rarely gets credit for it. Fluorescent green when it is early-harvest Picual. Pale gold when it is ripe and mellow. What changes with the oil, beyond flavour, is how the entire dish is seen.
Choosing the colour of the oil on a dish is a culinary decision, not a decorative one. At L’Aurea, we produce two oils with two distinct chromatic identities: Julia, with its deep olive green, and Aurelia, naturally coloured with plant-based pigments to a vivid, confident pink. Neither is a visual trick. Both are a statement that olive oil deserves to be seen — and that seeing it differently changes everything about the moment it is poured.

Frequently Asked Questions
Does colour actually change the taste of food?
Yes. Multiple studies in gastrophysics and neurogastronomy have shown that colour alters flavour perception by between 10% and 30% depending on the food and the context. Flavour does not happen only in the mouth — it happens in the brain’s integration of several senses at once.
What is gastrophysics?
A scientific discipline that combines experimental psychology, neuroscience, and food science to study how the senses shape the experience of eating. The term was popularised by Charles Spence, Professor of Experimental Psychology at the University of Oxford.
Which plate colour makes food taste better?
There is no universally superior colour, but white is the most versatile: it enhances the natural colours of food and tends to amplify the perception of sweetness and overall flavour. Black works well for dishes that are already dark, intense, and strong-flavoured.
Why do olive oils have different colours?
The colour of an olive oil depends on the variety of olive, the moment of harvest (early-harvest oils are deeper green; late-harvest oils tend toward gold), and in some cases the addition of natural plant pigments. In Aurelia’s case, the pink comes exclusively from natural beetroot pigments — with no effect on the oil’s organoleptic properties.
