What your eye color code means

Glowometry compares visible iris colors with the A10-T50 reference spectrum. The result is a closest visual match, supported by a sample of accepted colors from your photo.

A10 to T50 eye color reference chart showing blue, gray, green, hazel, amber, and brown irises
The chart is a visual reference. Natural irises contain multiple colors, patterns, and lighting variations, so a result may sit between examples.

What the result means

The code is the closest match within the A10-T50 reference spectrum for the visible iris colors in the uploaded photo.

Natural irises often contain several tones and patterns, so a result can sit between examples on the chart.

How does it work

  1. 01

    Eye landmarks locate each iris and exclude the center pupil and surrounding skin.

  2. 02

    Bright reflections, very dark obstructions, and colors far from the iris sample are filtered out.

  3. 03

    The accepted color distribution is compared with the reference spectrum.

  4. 04

    The higher-confidence eye provides the final code, and the pixel mosaic is drawn from accepted iris colors.

For a clearer result

  • Use a sharp, front-facing photo with both eyes clearly visible.
  • Prefer soft daylight and avoid direct flash or strong colored lighting.
  • Remove colored contact lenses and avoid heavy shadows across the iris.
  • Keep the camera level so the iris is not hidden by eyelids or reflections.
