Bay Roan Tobiano ?

She is either brown roan tobiano or black roan tobiano aka blue roan tobiano.  I can't really tell which from the photos.  

If you could get a closer photo of her face with the hair brushed out of the way that might help a bit.  I'm really leaning toward black roan tobiano.  I'm not really seeing enough brown around the eye and nose.  At times however, it can be really hard to tell them apart.  

I will get some extra pics, thanks :) She's definitely brown in the face, the light wasn't very good for these pictures, and try to get a better picture with eye and muzzle showing x

The pictures here below are from before i bought her x

Rather than fawn round her mouth its a kind of grey/smoky black, i will try to get this in a picture too, thanks so much for your help x

I have to say she is the cutest thing I've seen in a long time.  

She is a tough call.  I'm now leaning toward brown. However, I have seen tested black horses fade to look much like this and her flanks and other areas that would usually distinguish brown are hidden by the roan.  I think your best bet is simply to test and then you'll know for sure.   You can simply test for agouti.  If she tests A then you know she is brown if negative for A then she is black.  

Her offspring if bred to a "solid" sire should be half Tobiano and half classic roan.   I say should because in order for them to both be passed together some genetics shenanigans have to take place.   Genetics shenanigans do occur but are very rare.  

If you breed her to a black tobiano stallion and she is black you will get (assuming the stallion is heterozygous for tobiano) 25% Black roan, 25% Black roan Tobiano, 25% Tobiano, and 25% homozygous Tobiano.  If she is brown then half of all the above results will be brown and half black.  I'm assuming because she is so dark that even if she is brown is is heterozygous.  

Sorry I can't pin down her color better than I have but as I said she is one of those cases that is right on the line.  It's really better to just test.   

Thanks for your very kind comments, yes, i absolutely love her, i fell in love when i saw her, and paid £100 for her, absolute bargain :) 

I've got a silver dapple colt that someone has offered to stud with her but i'd like her to have a life first, she's a bit shy, and i want to build up her confidence so she will pass the right attitude to any possible offspring, 

Thanks for the suggestion to test for agouti, i was a bit confused as to what tests to have, you've been extremely helpful

I will post more pics maybe in the spring when she is unrugged and has her summer coat again, plus some head shots, and when tested i will come and pop the results on if possible x

Happy New Year xx
