Steel dust is not a color. I'm not sure where you got the term (if someone else said it earlier in the thread or someone told you it was a color). It may have been used to refer to a shade of gray in the graying process, which isn't uncommon (ie, rose gray). But all gray horses are just that: gray. Rose gray or "steel dust" is nothing fancy. It's still a gray horse. ETA: A google search of "steel dust horse" brings up pictures of a horse named Steel Dust and a few grullas. No, those are grulla horses. Nothing special about them.

And the non-silver grulla mentioned previously is not referred to as silver because there is a color gene named Silver that acts different, although that grulla may actually be colored what we consider to be the color silver.
So the horse on pg. 4 is considered silver?

NO. It is a name that someone slapped on that shade of grulla.

Silver should only be applied to horses that are carrying/expressive the silver gene.

How can you tell if it is?

The silver, silver dapple, chocolate flax or Taffy gene.

So what does a horse with the silver gene look like compared to grulla?

Thanks TX you posted ahead of me!

So someone said you could send a sample of the horses mane into somwhere to have the genes that correct? If so who do you send it to and for how much?

Oh yea I forgot how it shows up in the mane! Thank you texasgal for the link.
And horses with the silver gene I believe can be any colour, but will have a bi-coloured mane and tail, where the ends are a lighter cream colour, a grulla can have a bi-coloured mane, but the lighter colours would show up more towards the top of the mane. Like a dun. Rocky Mountain horses are basically brown horses with the silver gene I believe

Wrong. Totally wrong nokota. Please do some research before proclaiming what a gene does or does not do.

Silver tends to lighten the whole mane/tail. In some cases bleaching them of color completely. Silver only affects black based horses and does not show on red (similar to agouti).

As for testing US Davis does testing and so does Animal Genetics. Those would be the two companies I would go with.

So would you say this guy was carrying the silver gene. Excuse his mane, I had literally de tangled it before he was put out to the field, then a few days later BAM.

Black + Dun = Grulla

Black + Silver = Silver Dapple
