The reason Vessna scores olive for skin color is because of her HERC2 genotype. If she was homozygous there, instead of heterozygous, she'd score white skin.
HERC2 is strongly tied to skin color by GWAS. It's one of the most reliable ways of predicting skin shade in europeans, who pretty much unanimously have derived SLC24A5 and SLC45A2. But try explaining that to her... Her goal is badmouthing my tool, that's the reason she purchased the reports in the first place. She and her buddies here dont GAF about the genetics of skin color.

HERC2 is the gene associated with eye colour, not skin colour
SNPs, rs916977 and rs12913832
I am heterozygous for both of these SNPs
As Vessna has hazel-green eyes I'd imagine she would be heterozygous for these SNPs too
It wouldn't affect her skin colour
SLC24A5 and SLC45A2 are the genes associated with skin colour....the derived SNPs give Europeans light skin

go through these GWAS studies.
and type in "HERC2" into "Mapped Gene"

They very much do impact skin color. One of the biggest contributors to it in fact.

no. It is possible to score white, and even palest skin tone with my tool while having hetero HERC2. My tool's skin color prediction takes SLC24A5, SLC45A2, SLC24A4, HERC2, OCA2, ASIP, TYRP1, IRF4, and even MC1R into account. There's many combinations that can yield pale skin with darker eyes.

HERC2 affects primarily eye color, skin pigmentation is influenced by multiple genes. If HERC2 was solely responsible most brown eyed Europeans would have darker skin which obviously isn’t true. There are people like my husband who are homozygous for HERC2 but their skin is darker and tans well.
