Congratulations, you just realized that the PCA dimensions are built on reference samples.

Everyday, something new.

I believe this is exactly what's going on with the GEDmatch calculators too, like K36. The "Baltic" component was found by an algorithm, but labeled "Baltic" by the creator, because they felt that was the most accurate description.

However (and I think it was Davidski who explained this), because of the "calculator effect", these labels must be taken with a grain of salt or ignored entirely, and attention paid only to comparisons between actual genomes.

Lucas told that the K36 components were taken pretty quick and dirty and "Italian" is based on samples from Bergamo and one more town iirc. So these were not "found" by a calculator but simply determined. In fact it's irrelevant if they represent anything real or not because everything is anyhow then just compared mathematically. If it's labelled "Italian" or not labelled at all like a G25 component makes no difference.

My sister has a good phone camera so I'm hoping to get a pic of my eyes when I see her lol. I am curious asking people whether they think my eyes are light blue, blue, blue-green, blue with a darker center, or green as people seem to classify my eyes differently and I'd be curious what TA users think. Most people seem to think all blue eyes look exactly the same but I don't think that is true.

My grandmother had more of hazel eyes. Hazel eyes to me are a greenish brown.

These are what I would call have hazel eyes. Some people call eyes that are mixed with blue, green and brown hazel. It appears to have different meanings depending on the person.

The best defition of hazel is just "mixed color", then there is light hazel and dark hazel. Light hazel is mainly blue and/or green while dark hazel is mostly green and/or amber. Then aside from that is also the pattern of the colors, whether they are centralized, scattered, or otherwise. However, someone with light hazel eyes that are mainly blue would describe their eyes as blue to distinguish from the ambiguity of the term hazel, while someone with dark hazel eyes might describe their eyes as amber to distinguish from the popular assumption that hazel eyes are mostly greenish blue. It is not really a helpful word other than to describe that one's eye's are more than one color.

Before I got interested in physical anthropology I wasn't aware of the variation in blue eye color. Now, I find there are big differences between blue with yellow central ring, pure vivid blue, and grey.

What are you talking about. Hazel is from the hazel nut. Hazel it is not blue. It's a greenish brown color.
