Black. Very very faded.
She may carry cream, she may not. There is no visible phenotypic difference between black and smoky black. Single cream does not affect black pigment (or else buckskins wouldn't have black points!). Double cream does, but there's massive overlap in double cream phenotypes. You cannot accurately phenotype cremello vs perlino vs smoky cream.
Fading (as well as the light ear fluff formerly attributed to cream) is more likely to be due to nd1 than cream.
And nd1 is a mutation at Dun. All horses are Dun, nd1 or nd2 (or any combination of one or two of the above). An nd1 will have primitive markings but little to no body dilution (thus, not dun), whereas an nd2 has no primitives and no dilution.
