Such thing as a sooty bay?

Is there such thing as a sooty bay? If so, do you think Crimson is one? The first picture doesn't show his coloring real well because of the lighting but it was the only one I had. In the summer he turns bright metallic golden with black patchs starting at his neck and goes along his back to his tail. In the winter he turns a deep red and the black patches turn a charcoal grey color and extend further down his sides. His dad is a regular buckskin and his moms black. His full sister was a sooty buckskin.

I think they call a sooty bay... mahogany bays.

He's a sooty buckskin too. He's too light and golden to be a bay. I know a sooty buckskin QH that is as dark as he is too.

Bays that are dark like that are just referred to as dark bays or black bays.

I agree with P. He looks like a sooty buckskin as well. There is too much yellow in his face for him to be a bay.

However, yes, sooty bays do exist, and they are commonly called Mahogany bays, or dark bay in the western world. Here is a decent example of one.

Yup sooty can affect bay, as already noted. Also agreeing with P, I would say your guy is a cream dilute. I would lean towards a smokey brown though instead of buckskin, but it is only just becoming usual to differentiate between the two so P could have already deduced that too :)

Pretty much ditto what Chiilla said. I was going to say smokey brown over buckskin as well.

Oh interesting! And all this time I thought he was a bay, haha :)

Here is a pic of his full sister, who is a sooty buckskin, you can see she's a little differently colored.

I would call her a smokey brown too to be honest.
