Why does this ask questions instead of reading a photo?

Because a photograph is the least reliable evidence available. Cameras white-balance the whole frame, phone processing lifts saturation, and a flash fires straight into the iris and flattens the structure that distinguishes one category from another. A person looking at their own eye in indirect daylight has better information than any image they could upload — so the test asks that person, rather than pretending an algorithm could recover what the camera already discarded.

Can this tell me my real eye colour?

It can tell you which category your description is most consistent with, and how close the next one was. That is a genuinely different claim. Iris colour is not a fixed property waiting to be measured: it is what a specific arrangement of pigment and scattering does with whatever light is present, which is why the same eye is called green by one person and hazel by another and both are describing something real.

Why did it say two categories at once?

Because the two scored within a point of each other, and reporting a winner would be inventing a distinction the evidence does not support. Green and hazel, grey and blue-grey, and amber and light brown all overlap genuinely — the boundary between them is a naming convention, not a line in the iris.

Does this say anything about my ancestry or my health?

No, and it is built so that it cannot. It never asks about where you or your family are from, and it never infers it. Eye colour is influenced by many genes and varies widely within every population, so it does not support that kind of inference in either direction. It is not a medical assessment either. If the colour of one eye has changed, or a difference between your eyes is new, raise that with an optometrist or a doctor — a change is the one thing this page cannot assess.

What happens to my answers?

Nothing leaves your browser. There is no request, no account, no stored answer set and no photograph. The scoring runs on your own device against a fixed table of rules that you can see the output of on the result — every point awarded is listed with the reason it was awarded.

Why does the lighting question change my confidence?

Warm indoor light adds a yellow bias that reads as gold in an iris and can move a green result toward hazel; cool light does the reverse. Neither changes the category, but both change how much your observation is worth. The test lowers the reported confidence rather than silently accepting the answer at full weight.

What colour are my eyes?

Most eye-colour tests ask you to pick your eye colour and then tell you the eye colour you picked. This one asks what you can actually see — how much gold, whether the inner ring has an edge, how even the colour is across the iris — and works out which category that description fits. It shows you the runner-up, how close it was, and every point that produced the answer.

Nothing is sent anywhere

No photograph, no account, no stored answers. The scoring runs entirely in your browser.

It will admit uncertainty

If your answers sit between two categories, it says so instead of picking one. That is often the true answer.

It shows its work

Every point is listed with the observation that earned it. Nothing is inferred that is not on that list.

Before you start

Find indirect daylight — near a window, not in direct sun and not under a lamp. Look at one eye at a time in a mirror, close enough that you can see the fibres in the iris rather than an overall impression. Do not use a photograph if you can avoid it; if you must, the test will take that into account and lower its confidence accordingly.

Answer what you see today, in this light. If you find yourself wanting to answer with what you have always been told your eye colour is, that is exactly the habit this test is designed to look past.

What you can see

Look at one iris in indirect daylight, close enough to see the detail. Answer what you actually see, not what you have always been told your eye colour is.

In daylight, what colour would you say your eyes are at a glance?

Your own first impression is real evidence. It is not the whole answer, because a glance averages everything together, but it is the right place to start.

Compared with the rest of the iris, the ring closest to the pupil is…

The inner iris often carries more pigment than the outer. A warmer inner ring is the single most useful clue for telling hazel and central heterochromia apart from an evenly coloured iris.

How much brown can you see in the iris?

Brown is melanin seen directly. How much of it there is sets the broad category before any other clue refines it.

How much green can you see?

Green is not a green pigment. It is a moderate amount of melanin seen through scattering, which is why it shifts so much with light and why people disagree about it so often.

How much gold or yellow can you see?

Gold tones separate amber and hazel from plain brown or green. Amber tends to be evenly golden; hazel tends to be golden in one zone only.

Is there a blue cast to the iris?

Blue is scattering with very little pigment in front of it. Distinguishing a strong blue from a slight one is what separates blue from blue-grey.

Is there a grey, neutral cast?

Grey irises scatter light differently from blue ones, giving a flatter, less saturated result. Grey and blue-grey overlap heavily, so this question is often the one that decides between them.

How light or deep is the overall colour?

Depth separates the sub-categories within a family — dark brown from light brown, dark blue from light blue — which a colour name alone cannot do.

How it is arranged

Where a colour sits matters as much as which colour it is. These three questions are what separate hazel from central heterochromia, and an ordinary iris from a sectoral one.

Is the colour even across the iris?

An evenly coloured iris and a visibly zoned one can read as the same colour at a distance while belonging to different categories.

Does the inner colour form a distinct ring around the pupil?

A defined concentric ring of a different colour is what central heterochromia means. A gentle gradient is not the same thing, and is very common.

Does one wedge or patch of a single iris differ from the rest?

A differently coloured segment of one iris is sectoral heterochromia. It is a fact about geometry, so no amount of colour evidence should outweigh it.

Do your two eyes differ from each other?

Small differences between a person's two eyes are ordinary. A marked difference in overall colour is what complete heterochromia describes.

The conditions you looked in

These do not change the classification. They change how much confidence the result deserves, which is reported openly rather than hidden.

What are you looking in?

Eye colour is not a fixed property; it is what the iris does with the light available. Warm indoor light and camera processing both shift the result, so this changes how much weight the answer deserves.

How confident are you in what you just described?

If you found the questions hard to answer, the result should say so rather than sounding certain.

0 of 14 answered. You can leave any of them blank.

How the test decides

There is no model and no training data here. Each answer you give adds a small number of points to one or more categories, according to a fixed table written in advance — so the same answers always produce the same result, and the result can always be explained in full. Weights are deliberately small: a category should win because several independent observations agree, not because one answer was allowed to dominate.

Structural patterns are handled separately from colour. A wedge of one iris that differs from the rest is a fact about geometry, and no quantity of colour evidence should be able to outvote it — so if you report one, it is reported back to you regardless of how the colour scoring came out, alongside the base colour rather than instead of it.

Confidence is calculated from three things: how many of the eight colour questions you could actually answer, what light you looked in, and how sure you said you were. Leaving the pattern questions blank costs you nothing — not having a ring or a differently coloured sector is information, not uncertainty.

What this test will not do

It will not tell you what colour your eyes “really” are. Category boundaries are naming conventions applied to a continuous range. An iris that lands between green and hazel is not failing to be one of them.
It will not infer anything about you. Not your ancestry, not your family, not your health. Iris colour is influenced by many genes and varies widely within every population, so it does not support those inferences — and this tool does not attempt them.
It will not diagnose anything. Heterochromia is usually simply how someone’s eyes are. It is a description of an arrangement, not a condition. A change in eye colour is the case worth taking to a professional, and that is a question about history that no single observation can answer.
It will not tell you what you can and cannot wear. The styling pages it links to describe what tends to happen when particular colours sit near particular eyes. That is a starting point for experimenting, not a rule.
