Yea from the look of it they look like tans. Darker Tans tend not to have as much veiling as a beige when theyre born. Check the bellies if they wrap, theyre tans. if one is lighter, classify it as a beige ebony carrier. A good thing to do since you are breeding is always stating if an animal has ebony in it, even if it does not show ebony. Ebony will wrap the entire coloring, so if someone bought a beige and no one stated that the parents had ebony, the persons breeding intentions may be ruined. They may be breeding for show standards and beiges, and when the kits are born with dirty bellies, they'll be hounded on about that in shows.
So either way, if you are unsure its safe to say beige ebony carriers, until you are certain on color.
But regarding these kits, you will love to see how they grow and change color with age. Take lots of pics so that you can compare what they look like 6 months down the road. In most cases they change, and you arent certain if they get lighter or darker. Be ready for surprises with this litter!! theyre adorable!
