Horse coat color genetics is not something I know much about - the genetics always seemed complicated - but I would say that photo has been enhanced a little - that’s a perlino color (I think) - their skin and eyes are weird colors too - Akhal tekes come in other colors - and in this video they are almost metallic shiny but not quite like the photos that get passed around on facebook . Some of other colors - bay, black, buckskin and palomino show up here:

Here’s the perlino color I think (there is a color called Cremello in the Lusitano world, which I think is similar, but a little darker - they look sort of like palominos and have to have cream colored manes and tails).

Here’s a really good video of that wild color - you can see how shiny they are (this is the same horse from the second video, different lighting makes the coat show up differently - he looks more metallic in this video than the last)

Perlino is such a pretty color (variation?). This post caused me to spend a few minutes hours looking at you tubes of horses.

Here's one I watched a few times, showing the "floating" trot that some Arabian horses have.

As far as I know it's not trained (but it can probably be enhanced through training). There may be other breeds that have this particular gait, but I've only seen it in Arabians.

Speaking of, I also stumbled on this, absolutely straight from my childhood:

This is a video of *Bask, who set the standard for Arabian horses for decades we all expect to see today. I can't describe how absolutely beautiful he was. This was taken, I'm pretty sure, at Lasma Arabians near Shea and Bell Rd., likely in the mid-1960s or perhaps at McCormick Ranch. He also has the floating trot, which you can see in parts of this video. It was so fun to see him again!
