Oh just saw the parents colors at the bottom hiding there.
Well, they are all agouti if the father was truly a fawn (Aa, rr). Agouti is a dominant gene, RED is recessive.The father of this litter was my fawn hooded and the mother was a dumbo seal point siamese.
Sounds like the mother had a genotype of aa, ch ch.
I've read that if you have the Agouti gene with the siamese gene, it will end up with a washed out Agouti color. However these ones certainly do show the traditional gradient associated with siamese, and given at least one animal is black, the father may have carried the recessive black gene.
BUT, if the father was not a Fawn (which I highly suspect), where he was in reality a Beige (aa, rr), the babies would be marked siamese (this assuming the mother does not carry any "rr".
But, I can't say for sure because the pictures are quite dark, but I will concur with Crissy, that they are siamese and marked siamese, or rather, triamese.
