Need help identifying colors

[Castielle]

This is my first time posting here, so bear with me
I have a litter of 4 out of my holland lops. The mother is a VM Siamese sable (out of a BEW and a chestnut) and the father is a seal (out of a Blue point and a chestnut) in the last litter I had two seals, a VM Siamese sable and a VM that was either a blue seal or a dark smoke pearl
This time I’m struggling with identifying colors, all the kits were born pink, so I have a hard time believing that the darker kits are seals. I was initially thinking I had two Siamese sables and two smoke pearls

day they were born

about 1 week

Thanks for any help you can provide, these shaded babies are just so confusing!

I see 2 sables and 2 seals. In the newborn picture, I see at least 2 with dark skin, but I can't see too well. If they were born a bit early they can sometimes have lighter skin too.

Thanks!
Her last litter came late on day 31 and the seals were definitely darker that time. This litter came on day 30, so I wonder if that might have been what caused the difference in color
