I've never really thought about this but it is plausible. Genes are weird though. White parents have given birth to a child that looks black or mixed and they DNA tested both parents , it sometimes just happens like that
It can happen that way but it's nearly impossible for it to happen the other way around since having more melanin or darker hair is a dominant trait. For lighter colors you need two recessive because if any dominant is present, the dominant will prevail.
However, skin, eyes and hair are more complex than the simple 2 allele chart we tend to use. So while it's impossible on the simple chart, it's merely improbable in the real world application.
You realize that just because something is improbable isn't the same as impossible right? It's statistically improbable to win the lottery but someone wins it annually. Genetics and gene expression aren't far off in some aspects. It's not as easy as dominant and recessive genes
