The parents were a brindle and a fawn.
I have 4 that are these color(though the fawn color varies on them all)
At first I thought they were agouti, but then once they reall got their color in, I was sure.
They look fawn, expect for towards the tail, its much darker on the tips.

It looks to be an umbrous yellow, but it may be brindle. Be prepared to see amazing changes as they molt and acquire new and weird patterns of shaded areas. I bought a young mousie that looked something like this and was surprised and a little appalled to see it change on an almost weekly basis. These four have black eyes, don't they? If this one is a black eyed fawn, called red in this forum, the umbrous shading will may very well fade as it grows older.

I think that's just a sooty yellow, not umbrous. Sootineess like this is very, very common on petstore-derived recessive yellows and brindles (though I couldn't tell you why). Like moustress said, sootiness can change drastically with each molt but real umbrous does not. Umbrous is much darker and more solid in color and extends more-or-less all the way down the back (almost like a hooded rat's markings). Real umbrous is not very common in the US.

Umbrous shows up primarily on agouti or agouti-based animals.

I have some umbrous agoutis I will take pictures of tomorrow.

Here are two umbrous mice, both babies. One is heterozygous agouti, heterozygous umbrous (A/a U/u) and one is the PE-dilute version of that.







Because real umbrous modifies the dominance of A over a, the "A" along the dorsum reverts back to "a."

As you can see, they have ok type. But their color is a monstrosity. :roll: I keep them around trying to get rid of umbrous, and it just doesn't happen, due to the way that homozygous agouti (A/A) or homozygous non-agouti (a/a) can hide umbrous. You only know it's there on animals who are heterozygous Agouti (A/a). :x

Yep, they could. Sootiness appears in red/yellow and brindle. But they wouldn't necessarily have to be Avy/Avy. They could be Avy/A, Avy/a, etc. If I remember right, you sometimes get agoutis from your brindles, right? Then some of them are Avy/A.

They're one of two things:

unmarked sooty brindles

or

sooty recessive yellows

Either way, they're really cute. :)

As babies, when the dark tips of the hairs come in, they really do resemble agouti.

I cant decide out of this litter who Im keeping, they are all so cute! Usually I have no problem deciding who Im keeping,but its hard this time.
I figured I would have some agouti in this litter, so when I seen the dark tips coming in, I just assumed agouti, but I was wrong.
Im happy with them either being unmarked sooty brindles or sooty recessive yellows

I had some sooty unmarked brindles and some sooty RYs in this litter.
The brindles I kept are turning out to be sooty as heck. They had cleanish lines when younger,but now they are very sooty.
