You'd be equally likely to get a perlino, smoky cream, or another cremello because the cremello would ALWAYS throw a cream gene and then there'd be a 50% chance of the cream gene from the smokey black being passed down. If it only gets one cream gene, then you'd get smoky black, buckskin or palomino.
Let us see what the colour calculator actually says! (That's where I got the percentages before.)
25.00% - Palomino
25.00% - Cremello
12.50% - Smoky Cream
12.50% - Smoky Black
12.50% - Perlino
12.50% - Buckskin
Those are without knowing whether the cremello is non-Agouti, heterozygous for Agouti, or homozygous for Agouti or if it is a Non-Silver carrier, heterozygous Silver or homozygous silver. I just used the "Unknown" setting, but that can change the outcome drastically.
