Since Silver Mink and Pearl are genetically the same, you can also get inbetween colours, like Dark Pearl.

Today at least one breeder in Sweden is trying to create Blue Pearl - aaggmmP^ep^e. (Eye colour: black.) I think the g gene is best for this purpose, since it is suspected that many gg blues are actually aammgg. No photo yet.
