I'm not very good at uploading photos the way I want, but I'll give it a go and see if it works.
My TWH has seemingly changed color.
His papers list him as black.
He was black when we got him.
He stayed black for months, no stall, no blankets, without fading.
In the past couple of weeks, however, he has been looking more bay-ish and there's stripes in his coat (which may or may not be clear in the photo). It looks kind of like a brindle dog, right around the stifle/belly/flank area.
I am completely unfamiliar with adult horses (he's 5) changing color, so if anyone has any info on this, I'd appreciate it. Maybe he isn't *actually* a black horse after all...
Photo 1 should be a shot taken in the weeks right before we got him, est. November or December 2012. He's standing by a gate. (old color.jpg)
Photo 2 should be a shot taken earlier this week, August 2013. He's halfway under the run-in, but he's mostly still in the sun. (Color.jpg)
