What type of dun?

Ok, so I went on the color calculator today, but I don't know what type of dun Bella is. She is a Fjord, & according to the Fjord terms she is a "brown dun" but there is no option for this in the color calculator.
So, what type of dun is she? Bay dun or dunskin?

Bay dun I believe...

Actually I would say dunskin.

Do they have dunskins in that breed? I thought they were all plain ol duns...

Not entirely sure. They have brown dun (which is what Bella is, though there is no bay dun or dunskin specifically) red dun, white dun, yellow dun & black dun (grulla).

I don't think the color caculater is really breed specific though.

You need a cream gene + the dun factor to get a dunskin.

Jxclass19, no it's not. They have options for Dunskin (buckskin dun) or Bay dun. There are also other variations of dun on there but she's none of those I know.

So if I were to get her tested, what would I ask them to test her for? I need to take her into the vet to get her scanned for a registration chip anyhow, so I thought it would be good to check her.
Anyone know how much that costs lol?

Ok, so after looking basically in Fjord terms:
Brown Dun = Bay Dun (which would be what Bella is)
White Dun = Dunskin
Yellow Dun = Dunalino
Black Dun = Grulla
And of course Red Dun = Red Dun
