It turns out that the funny different color at birth is caused by the dilute gene.  We have 2 puppies in this litter that have double dilute making them "blue".  Their eyes will be a lighter color and the nose and leather pigment will be

 grey-blue.  This is still a very rare color especially the sables. 

The top boy is red-gold/blue sable,

the second is red-gold Irish Pied/blue sable

and the bottom boy is red/sable with black pigment.
