It is indeed fairly strange that the guard thought their skin was of an odd white. If he IS from Snakeland, then it should have been no problem with their skin - Ma has a white skin, and so does the entire family (although it was Ichika's old ghost-white skin treatment), which makes it obvious that white skin isn't such an uncommon thing in Snakeland.

Of course, you could also argue it happens hundreds of years after this incident, so their ethnicity could have changed since then.

Imo, I'd be a little vague in this particular point, just in case.
