A wild type, means that this color has no visible mutations regarding it’s color. It can still have all kinds of patterns, but they don’t influence the color mutations. Therefore, a wild type has so set genetic code. The genetic code of a wild type, depends on the inheritance form of any of the mutations. For example: the genetic code for Black is ‘aa’, thus the genetic code for a dark grey is ‘AA’ or if the wild type hedgehog carries for Black, the genetic code would be ‘Aa’. When you don’t know if the wild type hedgehog carries for Black, the genetic code changes to ‘A*’ where the asterix stands for an unknown allele. If Black would be dominant, the genetic code of a wild type would be ‘aa’.
Dark grey, the wild type in hedgehogs, has white quills with a wide black ring in the middle. The sides of these rings might be dark brown. The nose and eyes both are black. The ears and mask are a dark brown-grey color which does not fade much after growing up. If the hedgehog has ‘Algerian’ features (not to confuse with Algerian hedgehogs), the white in the quills may become a creamy color and they might have badger stripes, belly mottling, dark legs, cheeck patches and a more intense color. The skin on the back, between the shoulders, is anthracite.
If a Dark grey carries Black, it looks much like a Black before they fade. They are really dark and the brown hue a regular dark Grey has, disappears completely. But a Dark grey that carries Black, still fades and looks like a really dark anthracite color with a slighty brown hue in it’s mask and ears and the nose fades to a dark anthracite color.
