I've been having fun playing with the Predict Eye Color at GEDmatch. By uploading the results of my DNA test (which I took through Ancestry.com), the test predicted the following color:
I did read their page on accuracy which says, "FTDNA Illumina and Ancestry.Com results may provide a prediction, but generally there are not enough of the necessary SNPs for it to be
accurate." That being said, I think it was a pretty close match. Not exact, but close.
The Predict Eye Color test doesn't really tell me anything about my genetic ancestors, but since becoming interested in genetics, I have discovered that my brown eyes are not actually brown at all, but amber. Pretty neat! Maybe I should change my driver's license.
The test says, "Read rules from top to bottom. In some cases, a rule cancels out results from rules above it." The rules are based off of the SNP's (single-nucleotide polymorphism- see SNPedia). But basically, as one reads down the results of the test, a result can be canceled out. So, though one result lists a "weak amber gradient", the VERY next result lists "inhibit weak amber gradient." ROFL!!! But as you can see from my picture, I do have quite a bit of amber in my eyes.
One result lists that I have a gray ring around the outer edge of the iris, which I do. I didn't even realize that I had that!! How neat-o!!
Another fun test is their Rare SNP (Minor Allele) mutation test. Now, we all have genes that have mutated. This does not qualify you to join the X-Men (so sorry). It does qualify you to learn the various diseases that may occur because of these mutations. I will keep in mind that my DNA may indicate that I should really keep an eye out (at least while they are working) for signs of retinal and macular degeneration.
I am no expert at genetics and so I am going to be participating in some GEDmatch groups at Facebook to learn more about how to interpret the results. Pretty cool stuff.
Picture from GEDmatch
My eyes are a a lot lighter in color overall, especially near the outside of the iris, but the brown in the eye above is in my eye around the pupil.

Hi, I can't find that Rare SNP (Minor Allele) mutation test you mentioned. Can you tell me which site it's on please? Thanks
Unfortunately the mutation test is no longer on GedMatch. :-(
