|Margaux as a puppy|
As Magraux is a fawn, she is genetically sable. Sable is the dominant-most gene on the agouti locus and other variants of this locus appear to be absent from the Dane breed. As such, this dog must be AyAy sable.
This dog also has a mask, which is a trait preferred in fawns. Great Danes appear to be either fixed or near-fixed for the masking gene. As such, Margaux is most likely EmEm masked.
At least one of Margaux's parents was a Harlequin, and as such there was at least a 50% chance of her inheriting a copy of the dominant Harlequin gene, which is a gene that modifies the activity of the merle gene. Did she? Looking at her coat, her main body is made up of two different shades of red: a darker color that is essentially "average" fawn and a lighter color that is still definitely reddish. If she had received a copy of the Harlequin gene, those lighter areas would have been stripped down to white, but they were not. As such, she must be hh non-Harlequin.

Though Margaux does not have the Harlequin modifier, she is indeed merle. Due to the lack of white in her coat, she must have inherited only one copy of the gene. As such, she must be Mm merle.
Considering the amount of white that is seen in Margaux's siblings, there is a significant chance that she inherited some variant of the spotting locus. This locus is responsible for the white in mantle or "Boston" great Danes. The preferred amount of white on those dogs is almost always produced by Irish white spotting, and many Harlequins also have this variant due to the color class breeding of Harlequins, mantles, and blacks. This dog does indeed have a small amount of white, including all four feet. As such, it's likely that Margaux is Ssi solid carrying Irish white.
So, that's AyAy EmEm hh kk Mm Ssi or fawn merle (masked sable merle carrying Irish white).
