Frequently asked questions
- How does an eye color identifier work?
- An eye color identifier samples the iris pixels in your photo, filters out the pupil, sclera, and surrounding skin, and matches the remaining color to one of six color families: blue, green, hazel, brown, gray, or amber.
- What's the best lighting for an eye color test?
- Soft daylight from a window. Avoid flash and harsh overhead light, which throw off the white balance.
- Can I retake the eye color identifier?
