What colors are these horses?

[prplebird20]

I know I have a lot of champanes, and tiger eyes... And 3 duns.
https://www.horseworldonline.net/horse/profile/2985422 I don't understand how a dun came out of a seal brown and a silver dapple.
https://www.horseworldonline.net/horse/profile/2972631 Probobly a champane tiger eye of some sort.
https://www.horseworldonline.net/horse/profile/3001674 I know she's dun, but what exact type?
https://www.horseworldonline.net/horse/profile/3002986 Again, a dun.
Thank you!

First is Brown Dun. The sire is a cryptic Silver Grullo. He also has a silver bay dun offspring from a non-dun mare.

Second is Classic Cream (black + champagne + 1x cream) with a single tiger eye. (The sire is a silver perlino with double tiger eye. He passed on one cream and one tiger eye but not the silver.)

Third is Mealy Silver Brown Dun (brown + dun + silver + pangare).

Fourth is Bay Dun.

Also, I forgot to add: The sire of the third horse is not grullo but is actually a very dark Mealy Bay Dun (bay + dun + pangare) and the dam is actually a Mealy Silver Brown (brown + silver +pangare) rather than a silver smoky brown. She would have been born much more yellow if she was smoky, and you can see red edges around her mealy yellow areas, which she would not have if she was smoky.
