The Mystery Kit....Or What Color Is This Bunny?

Tauriel's kits are 3 weeks old now and SO cute.  Omygoodness they are so stinking fluffy, I just want to squeeze their little fat faces off!  

Ahem, but I digress....This is our mystery kit.  I think it's beautiful and am 90% sure it's a buck.....

Below it is shown with one of the black kits, and one of the castor/amber type kits....

Here it is from the rear....

And again with the other two colors of kits....it's on the far left.

And again, but this time with two castor/amber type kits...

And alone....it will pose nicely until I try to pick up the camera....typical kid!

And again from the rear...

Ok my rabbit raising friends!  Any ideas?  It doesn't really have a ring, perse, like an agouti rabbit should have, but it's really striking and quite lovely!  

Also, not sure if this helps, but Tauriel is a pedigreed rabbit and is an Amber.  Her dam was a Chocolate, out of two Chocolates, with the 4th generation being Castor to Castor, and Broken Lilac to Chocolate.  Her sire was a Castor, out of an Amber and a Red, with the 4th generation being Castor to Castor, and Red to Red.

Spartan is un-pedigreed, and when bred to Eden, a pedigreed Californian, she delivered all Black babies that are developing the silvering of the Silver Fox sire, but not the Silver Fox fur.
