Yeah it's a really weird combination of genes in that it virtually negates both genes in a sense. There are distinct markers that distinguish a normal to a black head spider now that people know more about the combo, but it's still really weird that it even happens. A bumble bee black head doesn't look like a regular pastel though so there's that.
