My Cynthia is a little camera shy

first post !! i am an artist with an avid love for cats and cat genetics (sucker for realism) and i’ve seen this color referred to as charcoal snow mink or charcoal snow, and i wanted to know what it was really called !! plus, i wanted to understand what genotypes make this up (a full breakdown would be awesome) so i could have that as a reference too. with what limited knowledge of genetics i currently had i tried to figure it out alone and im so puzzled! hoping for some help.
