Gene responsible for "rust" ?

[hex4kit]

My grey, dappled horse is becoming a warmer shade of grey as time goes by. What is the gene responsible for this? Is it sooty?

This mare is a silver on black. But what could explain the changing of the color, since sooty doesn't appear to affect black, because it's black... that's a good question.
There is one gene that will turn black hair toward the red spectrum, that would be Lp bronzing, however, if there was Lp switch here (to turn the bronzing on), there would also be varnish, and I see NO evidence of varnish at all.

There is an appearance change between the 4 year and 8 year gallery photo, but after that, I see no significant change, really not even minor changes. So, that's as far as my knowledge extends.

Thank you for the answer! I knew she was silver but I was wondering if sooty was behaving differently on other colours, thank you for clarifying that!!
I hope someone can pinpoint the gene,
I'll repost a pic when she is old too.

From my experience, that colour change is just what silver black does. Silver smoky black starts with a more blue tone and regular silver black starts with a warmer tone - both change to a similar, warmish colour by about 2, IIRC.

I never paid that close attention, so this is good information to me. I will be checking out if this holds true across the silver blacks (double creams, pearls, duns, etc) or with just the basic silver and black or silver and black with cream.

Thank you for that insight!

ooOOOOH thank you!! I did see some horses of mine going more golden without getting darker

Pleasure. As far as I know, it does hold true across all dilutions, it's just much harder to notice.

If I get any silver blacks, I'll also take pictures.

Should one of us make a topic on this forum to display findings related to silver black and it's dilutions?

The colour combination for which the tone change does not hold true is grey, as far as I know - grey on silver black and grey on silver smoky black foals will always be the same colour as an adult silver black or silver smoky black horse.

Something that I should perhaps clarify - it's not so much because of the silver that silver black and silver smoky black have different tones, it's because of black and smoky black. Black foals start out with a warmer hue and smoky blacks as a silvery-grey colour - this is what carries over to non-cream dilutions. So, I imagine a double cream silver black or pearl silver black will look exactly the same at birth (except the eyes, of course), with a colder and lighter hue than both silver and silver smoky black.

On the other hand, a silver classic champagne and silver smoky cream champagne will, once again, have a difference in with the non-cream having a warmer hue. The same applies to dun and should also apply to spotted and tobiano horses, but I don't work with those last two colours, so I can't be certain.
