More Colour Advice Needed!

[zarzamora]

Well I've been blabbing more of my limited horse genetics knowledge to my friends, and have got my friend interested in finding out more about her Cob's colouring.  To begin with I was sure she was a mouse dun, but another friend (who's also into her colours) thinks she may be sooty buckskin... I've grabbed some pics off facebook to show you, and see if you can point us towards some ideas before we send her dna off for testing.








Any help would be appreciated. Also- which tests would be most benefitial?

I have no idea about tests, but i'd say she's a mouse dun, just looks very light in the second and third photos, could be the lighting or her summer coat? The first photo definately looks like a mouse dun and the darker markings on her face in the third one also look like mouse dun. But i'm no expert, i'm fairly new to coat colours.
